I can understand the placement one. People spend a lot of time laying paths and a villager just plops on top of it. Designated no residence zones would be nice. Or a PWP to relocate a new house when it's just an empty fence. I see that resetting trick as making up for a bad game design choice.
Yeah. I've been placing lamp posts along my paths to prevent this from happening. But there's a limit on how many PWPs you can place. (For those who don't know, its 30.)
