Not yet. Though, even if they were, you would also need to get a
wireless LAN driver/firmware that supports non-zero Key ID for pairwise
keys, so this this require some more work.

For most use cases, CCMP is strong enough to be used for quite some time
without any rekeying, so the easiest workaround for rekeying related
issues is to increase the rekey interval. I would assume that the new
Key ID mechanism for unicast frames will eventually get deployed, but it
may take same time to get there.
