The list of chords is interesting.  I can't speak for all of the
users/developers, but personally I don't think I would be interested in
using the names of the chords that are on the left hand side of that
table.  I'm less interested in having a unique name for each chord, and
more interested in having a structure that supports chord characteristics
(such as the quality which is listed in the table).

I suppose that there could be some interest in chords that are not in
standard temperaments, but I don't think that is the focus of interest for
this project.  I don't believe we are trying to expand the range of chords
that LilyPond can capture with this project as much as we are trying to
improve the semantics of what we already have.

That being said, I don't believe there would be any problem with adding
non-standard chords in addition to improving the semantics.

Congratulations on your dissertation completion.  That's a big step!  If
you're interested in the project, we'd be delighted to have you apply.

Thanks,
