Are there any technical reasons why whatever method a2jmidi
is using is not adopted for the backend ? Maybe it's just a
matter of manpower, but OTOH this situation with the backend
failing to do 'the right thing' has existed for quite some
time now.

it is just a question of manpower. i already did factor out most of the a2j* code into an internal client that jackd could load. the problems remaining:

    * whether or not to provide a new way to load such clients (e.g. on the jackd command line)
    * what to do about the dbus integration that is used in a2jmidid to pick up the arrival and departure of
           new MIDI interfaces

I'm not sure that dbus is actually necessary for this - i think the sequencer API has its own way of announcing new clients (and the departure of existing ones) - but I have not investigated it enough to come to a conclusion.
