I think the appropriate question is not "have we still got bits left?".
It should be more like "under what plausible scenario would it be useful
to grant somebody CLUSTER but not VACUUM privileges on a table?".
I'm really thinking that MAINTAIN is the right level of granularity
here. Or maybe it's worth segregating exclusive-lock from
not-exclusive-lock maintenance. But I really fail to see how it's
useful to distinguish CLUSTER from REINDEX, say.
