Oh, yes, the implementation may make decisions, but the local user
always has control.
A revocation certificate is really just a signature.  If I remove it
(gpg --edit-key can do this easily), then my local copy of the key is
not revoked any longer.
An expiration date is just a time_t.  If I set my clock back to before
that time, the key isn't expired any longer.
The user always has control.  There is a convention between
implementations that they won't use a key that has a "revoked"
certificate attached, but what I was saying was that there is nothing
in the cryptography that prevents this.
