On the other hand, being confronted with all of these at the same time, and having to find all instances by proof failure is time consuming and can be extremely frustrating when you have to hunt in hg history for what something has been renamed to.
Side-remark: About 50% of the time I do look at the hg history (using e.g. "hg
grep --all") to see how names evolve, and what needs to be done. This also
applies to magic (simp add: ...) or (simp del: ...) details.
