No-one uses MIDI 2.0 yet, we don’t need it! MPE (https://www.midi.org/midi-articles/midi-polyphonic-expressio...) is only just being adopted (with poly aftertouch instruments and keybeds like the ones in the ASM Hydrasynth).

MIDI has proved amazingly resilient, whether over 5-pin DIN, the increasingly common TRS 1/4” jacks (common on Eurorack or guitar pedals, where space is a premium) or the utterly ubiquitous MIDI over USB. (And ethernet, can’t forget that). Everything digitally controlled speaks MIDI - and not just music, the stage lighting world is all MIDI too. I think that there is a real case that it’s the second most successful wired physical-layer protocol behind Ethernet.
