I haven’t but I’m not opposed to that eventually.  As Werner notes there is 
still a lot to do.  I haven’t done anything with refining the appearance.  I’m 
just trying to get the ball rolling by getting all the “moving parts” in place 
(since I’m already familiar with the techniques for implementing alternative 
notation systems in LilyPond).  

Ideally someone who uses and really knows Jianpu well could take it over and 
refine it. (Maybe David Zhang? or Silas Brown who did the “jianpu-ly" Python 
approach? [1]  Maybe some of the appearance work could be repurposed from the 
output of “jianpu-ly”?  I haven’t tried it.)  I don’t really have the time 
right now to refine it and see it all the way through to adding it to the core.

Yes, that’d be a problem.

Thanks, although I’m not sure it’s worth starting that discussion just yet…
