The 'prune --expire' behavior is based on object mtime (i.e. file modification time). That is lost once something is packed right?

I was thinking that either repack or pack-objects could be modified to unpack those unreachable objects and leave them loose, and also give them the timestamp of the pack file they came from. Then the --expire behavior of git-prune could work normally and remove them. This seems like it would work nicely since prune follows repack in git-gc.
