- Climbing long ladders is often necessary (deep mining for key
materials like molten rock) and boring.
- Running-up-ladder prevention hasn't really been working right
anyway; it's trivial to bypass it by "wiggling" as you climb.
- Ladder running prevention was done as a "realism" thing, which
we are always prepared to sacrifice if it interferes with fun.
Instead of simply allowing the previous "exploit" allowing players
to run up ladders as long as they're "running" into them, actually
allow fast ladder-climbing (and up-swimming) as a first-class
feature.
