Yes, but that breaks *all* working copies, whether they are affected
by the changed history or not. What would be vastly better, I think,
would be that only "working copies containing traces of the changed
history" would be broken. Thus salvaging "working copies with only
non-affected subtrees" and "working copies at an older working
revision".
Especially in the case where you're obliterating the most recent
revision(s) only, that could be a big deal.
