- Convert more things to autostart DNTs?

- Unify the "node destruction particles" system.  Allow complex options,
  like alternative node def, particle def, disable on silk touch.

- A wooden plank appeared to have decayed in place of a scaling node;
  could it be a problem with ABM muxing?

- Switch ents to using on_step moveresult for collision detection
  instead of checking nodes directly.

- Organize into modpacks for layers
	- Compat
	- Util
	- API
	- Natural
	- Tech

- Try to detect and separate out translation strings coming from
  non-core mods so we can consistently generate the game translation
  file without having to disable mods.

- Automate uploading translation source strings?

- Test nc_wield with items that have their own visual scale.

- Flammability ABM ordering.  Always do extinguish check after ignite
  checks or vice versa, so suboptimal firestarting is consistent

- Make door pusheability customizable
	- door_can_push or door_cannot_push groups/flags or something.
	- Allow override of standard falling_node check.

- Overhaul player health to work entirely virtual
	- Raise max up a lot to make room for fine grained falling
	  damage so we can raise threshold
	- Consider falling damage add percent to all nodes?
	- Add API for doing fake damage effect using set hp

- Allow optics pending transaction to be flushed early
	- Optics interacting with doors are out of sync
	- May need to commit the optic state immediately when triggering
	  doors so they get the correct current state.

- Consider full eversion of event handlers
	- Disallow (or automatically convert) traditional single-handlers
	  on all definitions
	- Use a register_on_something() method to hook pretty much
	  everything

- Unify mkreg
	- Add validation/modifying and order comparison funcs
	- Use for recipes, mapgen_shared, playerstep, etc.
	- Consider replacing with register_generic():
		- Allow lazy registration, i.e. a register method that can
		  register for things not yet defined, and allow later registration
		  of the registration definition that will pick up those missed.
	- Define order for inv tabs

- Transactional api ref localization
	- For certain large computations, like an optic processing, it may be
	  worthwhile to capture some often-repeated functions like minetest.get_node
	  as locals.
	- May need to test performance on a non-JIT build, where this is expected
	  to have a larger impact, since JIT probably optimizes the difference away.

- Some time-integral processes are not resetting when prereqs removed
	- Cooking resumes instead of resetting when fire removed.
	- Leaching resumes instead of resetting when water removed.

- Make leaf decay group-driven for mod applicability.

- Switch some extended attributes to first-class support instead of modifying
  definition at registration time.
	- e.g. the way drop_in_place used to be an after_dig_node hook
	  modifier but became first-class.

- Add a nodecore.inherit_node() helper that registers a node as a
  modified copy of another definition, e.g. for planted eggcorns copying
  dirt, door panels copying original materials, etc.

- Add an on_falling_check handler to replace check_single_for_falling custom
  hook in writing, and possibly other places.

- Should we create "recipe groups" to make it easier to specify
  equivalent recipes for hint purposes?

- Need to find a way to make AISMs work with falling_node.
	- Create ItemStack, run hooks, try to convert back to node
	  (assume node and item meta map 1:1) and if it fails then
	  spawn an item_ent.
	- Need this for amalgamation remelting.
	- Would it make sense to unify the item and falling_node ents?

- Unify sponge growth logic so it can be used for mapgen, to ensure
  that spawned sponges match naturally-grown ones?

- Easier recipe API:
	- Use ascii art like ezschematic?
	- Aliases like "sides"/"corners"?
	- Make 3x3 recipes easier to define.

- Standardize visinv access API
	- stack_access(pos, node, dirfrom) - return booly
	  whether access to inside stack is allowed.
	- Use for shelf API.
	- Use for touchtips inv access.
	- Genericize sponge logic using stack_access API

- API for recursing through embedded inventories, e.g. in totes.
	- Lux reaction cannot sense other lux inside totes.

- Scripts to validate dependency graph.
	- Tag deps directly in code at place of use.
	- Auto-generate mod.conf / depends.txt

- API Cleanup
	- Further nc_api break-up, clean up util functions.
	- Heat API
		- Quenched, Flames as numbers or nil?
	- Unify nc_items and visinv API.
		- Stack nodes are "special", get first-class support.
	- APIs for different kinds of "neighbor" scans
		- Face, edge, corner touching
