I would run restore twice in this case:  once without -x, specifying just the deleted mailboxes (you can use "cyr_backup list mailboxes ..." to get a list of the mailboxes in the user's backup).  And once with -x to get all the expunged stuff.  For the -x invocation only, I would probably also use the -M option to dump all the recovered stuff into a new folder, so they can easily tell it apart from any new mail that might have arrived coincidentally at the same time.

We kinda had a similar idea!  Putting it all into a folder with -M is much easier than setting up a separate server, but it'll lose the folder structure.  Recovering to a separate server means the folder structure can be preserved.  I guess it depends on the specific recovery situation, and how hard it is to spin up a server in your environment.
