If your definition of "elegant" is equivalent to "peg-whittling."

the CLASS field was included back in the dim times before IPv4 had
become entirely ubiquitous, and there were competing networking
protocols with competing addressing notations, and it made perfect
sense to imagine serving the network address of a networked resource
under the same name in DecNet, IPX, Appletalk, etc formats. Thus the
lack of differentiating.

After background pondering this for a couple hours, it seems like a
reasonable modern use, given the unchallenged sovereignty of the IN
addressing scheme, for an additional class, might be geo-coordinates.
A LL class might request latitude/longitude coordinates of a named
resource.  Physical coordinates are in wide use and are deeply
separate from IN addresses in the ways that might justify assigning
them a CLASS designator.
