In the case of the generic DELETE (without NONVSAM), FDRABR intercepts the 
HDELETE issued by IDCAMS, and it works fine (IIRC).  The interfaces are not 
compatible, I agree that it would be beneficial, but someone (IBM) would have 
to define such an API - and share it with the ISVs - in order to have it work 
that way.

It appears that the consensus of this thread is that in the absence
of the NONVSAM option, IDCAMS converts a DELETE request for a migrated
data set to HDELETE.  If IDCAMS doesn't know whether the migrator is
HSM, FDRABR, or some other product, how does it know what component
to issue the converted DELETE to?

If the interfaces are compatible and, as I still believe, the migrator
must know the VSAM-ness in order to perform the deletion without recall,
it could as well return that characteristic in response to an HLIST or
equivalent API query.  There's considerable value in avoiding recall
of an entire data set in order to obtain one bit of information.
