As a user with lots of MIDI equipment from the 80ies, I would prefer a 
separated JACK application doing this. It's not only for Linux, but for 
all computers and stand alone equipment that MIDI sync among some 
combinations of applications and/or hardware is ok, while it isn't ok 
among other combinations, e.g because of master and slave issues and 
sometimes just because of voodoo.

If Linux apps would use JACK transport the coders only would have to 
take care to handle this. Just having on app doing sync among JACK and 
eternal MIDI would reduce the risk of trouble. Btw. MTC should be part 
of such an app too ... I didn't read the whole thread, perhaps this was 
mentioned before.

Just a note by an user, becuase of "the MIDI stuff could be implemented 
as a separate JACK application": Full ACK.
