I don't see how revocation might help against potential compatibility issues caused by careless and ignorant site operators: If an operator ignores all communication from his CA and uses a SHA-1 certificate on a server where it causes issues with its users, he will also happily use a revoked certificate (and advise its users to switch off OCSP). From the point of view of a user, a Firefox error message sec_error_revoked_certificate is the same as sec_error_sha1_untrusted.
