Pressure Plates in Villages

Something strange about villagers that I've seen is that in certain instances, they don't close their doors at night. I'm not sure if it's because of multiple villagers entering the same home, or if they reach the bed before they close the door. Either way, it leads to villagers being attacked by zombies while they are asleep. (Yes, I am sure that I am not the one leaving the doors open)

I feel like if a village that the villagers themselves built isn't compatible with villager AI, then it's not how it should be. I think that village houses (at least the ones with beds) should come with pressure plates inside of them, allowing villagers to automatically close their doors before going to sleep more consistently, which would help keep the population alive. 

Of course, you could change the AI, but this would be far easier, and it's not like pressure plates are foreign to them, as certain village houses do have them on the "tables".

That's all
