I agree, that's an infrastructure whose time has come and gone.  (Not
much call for traditional ROM monitors when one can just as easily
boot to a real OS instead!) We would see references to people using
monitor backends from time to time, but I haven't seen any mentions
(with either new or old GDBs) in several years.
