Of course, yes.  For revocation this is the correct approach.

Supposing you are unlucky and strange guy named Eve has the private key
from your cert.  Now there are two people who can revoke your certificate:
you, and Eve.

Reissuance should of course still involve fresh Domain Validation.  Which
is only moderately secure, but that's as good as PKIX can ever do for you
today.
