The workarounds (archived original in case I need to get access to unmodified files and frozen effected track) are great, but they're definitely things that can slow a session down dramatically when you're doing a lot of tuning work.
If I've got, say, 50 takes of a backing vocal choir that I'm tightening things up on, and I'm working through each layer to see what needs fixing (if anything - choirs are often best left untuned) then this is something that'd take forever to archive/freeze when it should be a case of "let's fix this quickly" and not worry that what you're doing is the last opportunity you have to work on it in that manner.
The other thing is too, if I've finished working on a tuned lead vocal track and I've bounced it all down, and then decide to do a vocal double and use VocalSync to tighten the timing up, then I'm kind of stuck if Region FX is busted.
Semi-related to this: I'm actually surprised that bounced clips have no name. Is that a normal thing? I've never noticed that before. It would make sense that it should say SOMETHING in there (Record nnn (bounced) or something?)
Anyway, really hoping this is just my installation that's the problem rather than a bug or a design choice because it's a bit annoying.
