It is indeed a no-brainer: no downside, and a heck of a lot of wins.  I
was very disappointed when it was rejected the first time around :/

Nitpick:

I realized an oops on my part here.  (Unlike LV2) Jack /events/
themselves don't need a type field, since a port would presumably only
transport events of one type.  So all events can use the same
(conceptual) "struct" and API, the /port/ type would say what the type
of the events actually are.
