Right, that's a pretty big argument for favouring Windows integration
rather than Linux compatibility here. So what would be the
consequences of not allowing the current working directory of a
running process to be deleted?

I'm not convinced such a compromise would be worthwhile, because it
would forfeit Linux compatibility while still breaking some
Win32-using programs. I think it should be one way or the other:
either stick with the current approach, or always sync the Win32
working directory up-to-date (except when that's not possible).
