Greetings to you both,
Well, I for one am quite happy to see that Jan’s still around (even
though you guys have every reason to feel tired)...

Schikkers-List was an awesome idea (it still is), and I’ve been very
excited about it since Jan first announced it. As far as I’m
concerned, it’s definitely not off the table.

Getting LilyPond to work with Guix is also a promising lead (I’ve been
playing with NixOS for the past decade and I’m delighted to see the
concepts behind it gaining some traction lately).

Although an incredibly frustrating PITA on many levels, Guile v2 is
here to stay so getting both LilyPond (I believe we’re almost there
yet, aren’t we?) and the upstream code ready _does_ matter,
considerably. Thus, although I’m not actively contributing at the
moment (other than the occasional pep talk :-) I’m glad you guys made
this fragment of your proceedings public.

I’ve been building Lily with the --enable-guile2 flag for the past six
months or so (well, as far as issue #4814 with GCC6 has let me), and I
haven’t been running into any problems in my day-to-day work; I’ll
happily keep playing guinea pig until we can ship unstable releases
with guile2 by default.

Re. Guix; I’ve just cloned and built Jan’s branch and this is as far
as I got in just a few minutes:
