Can confirm in 1.21.

Hi there.
In 1.14, this won't stop villagers getting work, but:
minecraft:village/snowy/houses/snowy_masons_house_1
minecraft:village/savanna/houses/savanna_library_1
These two stop villagers getting into the room,
minecraft:village/taiga/houses/taiga_library_1
This one stops vilagers to touch thr workstation.
