The bug
Taiga villages still generate with trapdoor troughs.
Since MC-50556 was resolved as WAI, this should not be the case.
Possibilities to fix this bug
Fix #1: Remove these decorations from the structures
Fix #2: Make mobs no longer stuck in the trapdoors
Fix #3: Make mobs auto-jump if there is a trapdoor in their way.

Please do not assume that Mojang has not addressed this in an upcoming release.

This still being a thing in 1.16.5 shows that it has NOT been addressed.
WAI? Villagers being stuck in these things is really intended?
