Not sure if someone brought this up already, but I wonder if it's possible to instance the whole friggin' district. Get three or four of them for each and suddenly plot availability multiplies by the same number.

Individual instances would still have some advantages though. You likely wouldn't have to load in between interior and exterior for example. That alone would be a helluva QoL change. I still like the idea of having neighbors though, even though nobody is ever outside or home.
