Bushrod "Feedback" to deletion error handling

[crspybits]

C: SharedImages can now cope with users removing or renaming files in their own cloud storage!

R: Do other users get to keep their copy?

C: Sure... until such a point as they remove their app and try to re-install, re-download. In that case, they won't be able to re-download files that owning users removed. Or try to re-install/re-download on a new device.

R: Might want a way to save your own copy of missing files to your own storage to prevent that issue.
I’d rather it gave me the option to make my own persistent copy.

R: It might be tough to know something has gone missing until you go checking for it, so you’d need a periodic sync check to persist from your local cache. Definitely complicated.

R: But then every user would make their own persistent copy. And then where would the conversations live?

C: I think someone would have to take new ownership.

C: Just to make sure the context is apparent, this isn't really a "take it down" situation. That would be deletion from the UI. This is a -- some user goes into their Google Drive directly and removes or renames files. A, hopefully, rare situation.
