The syntax may very well be a bit odd, but a few minutes of
intellectual poking with supersede leads to a simple solution for all
of the problems mentioned so far.  That is left as an exercise for the
astute reader.

Please feel free to add the security tag once your request for a CVE
id goes through.  For now, since there are simple workarounds, and
given that this is an upstream design flaw rather than a
Debian-specific issue, further effort on solving it should go there.
Good luck!

Best wishes,
