Resolution: Works As Intended
Taiga villages still generate with trapdoor troughs.
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.
