Revocation lists get huge, ultimately becoming another reason to limit cert lifetime (you don't have to tell people you revoked a certificate which is expired naturally).

Very few things check revocation, unfortunately - it puts an extra hop on the fast path of connecting to a server. OCSP stapling is pretty much the only thing a browser would care about - having the server fetch a signed OCSP response that is good for a limited period of time (say, hours), and send that along with the certificate during negotiation.

Or, you could just have the server fetch a certificate thats good for a limited period of time.
