You *can* revoke a single subkey (although gpg is able to use it anyway, I
think), and you can revoke the signing key (which is the "main" key).

It would be possible to remove userids from keys, but when you upload it to=
 a
key server, the userids are merged like the certificates. So, you cannot re=
move
a userid from a keyserver, like you also cannot "remove" a key.
