I know, and BTW a great resource your keyanalyze statistics, and your
work on fixing the hpk keyserver bugs, thanks.

Yes, I have seen the same behaviour in a sks keyserver. I see now that
it laso store multiple signatures for subkeys also, due to changing the
expiration time, I guess. See:

Ah, that's what confused me...

But older servers are buggy and don't handle properly multiple subkeys
among other things (again, AFAIK).
Thinking about this (and that's where gpg come into play), if older
versions of self-signatures are of no practical use, and may only bloat
the public key, it should be stripped at download time by the
"keyclient" (gpg in our case), although it are preserved in the
keyserver for some reasons (you should known better).
