I am also very bothered by this. I developed rtpmidid just to be able to use rtpmidi on bitwig.. and I need to use the virtual midi device hack.

I was just thinking if there is a way to ask for features.. and there is! https://bitwish.top/c/features/5

I will add the request for ALSA sequencer devices, which I think should include Jack ones.. but I will investigate this further, as maybe I'm wrong. There is a bridge for sure.

Anyway just don't hijack the MIDI device and be nicer with the linux MIDI ecosystem is a must.
