nobody hates you, but it is irritating that you would say stuff like this.
the history of JACK MIDI has very very little to do with Ardour, and indeed
was conceived long before any work had even been discussed that would make
Ardour a MIDI sequencer. not only that, but the guy who implemented most of
JACK MIDI went on to work for a competing DAW company!

so ... no, the goal was to allow the ecosystem of JACK clients to exchange
MIDI data with (a) zero copy (b) sample accurate timing (c) correct thread
semantics for synthesis.

i have no idea why you find it necessary to disparage JACK MIDI in the way
that you have done above. i think there are many perfectly sound arguments
against JACK MIDI (they are almost symmetrically matched with arguments
against the ALSA sequencer), but the "JACK MIDI was conceived so that
Ardour would the rule the world" is silly and insulting.
