Yes but if you compare this with the CA having the private key, you are going to notice that you revoked and issued a new key; also the CA will have your revocation log to use in their defense. At minimum it is detectable by savy users who may notice that eg the fingerprint for the key they have doesn't match with what someone else had thought was their key. > I agree with Michael H.

Key pairs should be generated by the user.
