I think it's hard to tell what the demand for microtonality would be if it were easy to do rather than hard. Right now if you want to do non-12-EDO music, there are roadblocks everywhere. Instruments are practically non-existent, aside from continuous-pitch instruments like violin or trombone. Standard notation works against you. One would think that electronic music would be the one place where microtonal music would be easy, but no. I don't really expect mainstream music to suddenly start making extensive use of seven-limit just intonation just because MIDI 2.0 has per-note pitch bend, but for the people who care about it at least we could see a lot more interest in expressive instruments and non-12-EDO musical performance. Even if it's only 5% of musicians who care about any of this stuff, that's still a lot of people.
