Good idea, can you file a github issue?

It's not like the CVE issue and the object count mismatch are related.

I just pointed out you must follow the repo upgrade steps first because 
otherwise borg might consider some archives without a valid tam as crap 
and would DELETE them.

Archives without a valid tam may exist in old repos due to:
- a bug in older borg versions, especially in borg rename and recreate.
- an attack by a malicious entity

(see the upgrade notes for more details)
