Yes, but that's the application, not the save. Realize that with a full save
you really have the same issues, just a different twist.

If you take fulls every night, then you can recover to a particular night.
But the deleted members from the previous days are still deleted.

With changes, you can still recover to that particular night, you just may
have members from the full save that are not in the changes because they
were deleted on an intervening time period.

Again, this is an application consideration that has implications in the
save/restore process. All of your applications do. That's why when someone
asks, how _should_ I do my backups, the answer is _always_ "it depends".
