I don't remember exactly if it was in apt-get, but even if it isn't,
it's not that useful to have a real keyring for the revoked keys. What
is really needed is a way to identify a key to be removed. If we had a
real keyring we would just add another command to the pipe to get the
key IDs without any real gain. So, using the IDs from the start is all
that we need.

I think I forgot to write the corresponding documentation when I sent
the patch . Sorry for that...
To summarize, when I made the patch, I worked with 3 sets of keys:
current, deprecated and removed. Current and deprecated would still be
added by the reload operation (now renamed to populate). Only keys in
the removed set would really be dropped from the keyring. In that
context, I thought of adding Holdkey as a way to allow the end user to
avoid having to re-add a needed key if it was marked to be removed.
My initial use case was based on the my personal premise that a
ex-developer's key would be removed by the time of his departure. In
that situation, maybe his key would still be useful for other personal
repositories he could keep maintaining elsewhere. But if a developer's
key is kept even after he leaves, the premise is not true anymore and
HoldKey would lose a potential use case. But maybe it is a matter of
distribution policy, so it could still be useful to have such an
A: Because it obfuscates the reading.
