self.repo.wvfs gets repeated often enough that it's probably worth extracting to a local variable

1980–1982

I'd prefer to see this addition in the patch that needs it. At this point it's not clear what this is for.

Also, with this code here, it seems a little unnecessary for the block above to delete parent directories if we're just going to create them again here. Am I reading that right?
