If you are talking about the split descriptor/callable returning
decorators, I'm not convinced that having decorators split based on
which (one) produce descriptors and which (ones) produce callables is
necessarily a good idea.  Certainly it is explicit, but so is having it
be the /last/ decorator (if we use left-to-right application or first if
we use right-to-left application) when we have a single decorator list.

Perhaps not, except in the case when you expect your implementation to
document itself (I do most of the time).  The use of a classmethod
implies something, just as the use of a staticmethod or instancemethod
implies other things.  Using one for another may be confusing to anyone
reading code later.

Oops, I forgot the colon and indentation, it is fixed now.
