This is not true.  The mild error reports are due to a different sort
of keyserver corruption (subkeys).  There aren't many keyserver issues
with photo IDs - basically, it either works correctly, or it rejects
the key completely.  No gray area like subkeys.

That is out of date.  The updated specification supports user ID
revocation.  In GnuPG, use --edit-key and then "revuid" (the old
method of revoking the self-sig works as well).
