Vacuum non-clustered tables only

I think I know the answer to this, but...

Is there a semi-easy way vacuum all tables in a database *except* those
that are clustered?

(VACUUM [full]; CLUSTER;) is a huge waste of time and resources when you
have clustered tables.  If there isn't a way to do this, can we consider
it a feature request?

Perhaps "VACUUM unclustered" or something?
