I certainly hope that in the near future, digital transcriptions are easy enough to come by that you could effectively just change the font from one notation to another.

I know there are a lot of judgement calls in typesetting music, but that's true of text too, and we have some pretty good algorithms for doing so these days.

All that said, I have a lot of reservations about this particular notation, but I think there's certainly room for improvement even inside the current system. Letting the back catalog of work hold notation back isn't healthy.
