I don't think 'atomictemp' can be generalized well to the other vfs operations. And atomictemp=True doesn't mean repo.lock/wlock is unnecessary.

If people starts wrapping pathauditor, adding atomictemp later would results in breaking their wraps. Do you want me to send a V4 to remove the atomictemp?

IMHO, the interface of audit() and ward() in the original series is pretty basic. 'mode' might make some sense for all file operations, but 'atomictemp' wouldn't. > Do you want me to send a V4 to remove the atomictemp? Yeah, if that makes sense.
