You Shall Not Climb!

"You Shall Not Climb!" (YSNC) is a Fabric server-side mod that takes away an ability to climb ladders from mobs that are not supposed to have it.

MC-148545 "Mobs can climb ladders" was labeled by Mojang as "Works As Intended".

Obviously, this doesn't make any sense since it's expected that most of the mobs don't use ladders deliberately.

It feels more like a side effect that is actually easy to fix, which is what this mod does.
