I like this message. However, as others have noted, I didn't get that
message from the slides.

Where are the thousands of Euros bounties for the LaTeX-based solution? I'm
not aware of *any* thousands of Euros bounties for anything on LilyPond.
This is a serious question, not a rhetorical question, by the way. I have
looked at the issues with Bounty tags, and the only one I can find that
seems to be relevant to this discussion is "support for footnotes and/or
endnotes". That issue makes no mention of a LaTeX-based solution.

I think that "these issues are orthogonal to the current work in the
LilyPond project" carries a much different connotation than "the community
has no interest in these issues", even though they may cover the same facts.

May I suggest that "Publisher-Grade" is perhaps a misnomer? This makes it
sound like we can't produce *any* publisher-grade music without footnotes,
or endnotes, or widow/orphan control. Perhaps an adjustment to the title to
"Publisher-Grade Critical Edition" would help clarify things.

I'd appreciate anything you could do to clarify (for the -devel list and
for the bug tracker, not necessarily for the paper) the status of the
"vendor tree" relative to inclusion in LilyPond. For example, if there's a
patch available that is just missing its test case, then we ought to have an
issue about that. If there are other patches that are not yet up to
LilyPond status, but might be able to get there, it would be nice to have
them listed as issues with patches attached. Then we'd at least know that
there is work to be done. As long as the patches are only in your vendor
tree, the community can't really help.

There are two ways to ask for help. One way is to ask for somebody to
implement a feature. The other way is to ask for guidance in how to
implement the feature oneself. I'm not aware of any "guidance" requests
that have gone unanswered. On the other hand, there are *lots* of feature
requests that go unanswered.

Nobody *ever* raises their hand and says "I'll do it" for a feature request
in a new area. If I had just asked for somebody to implement fret diagrams,
I doubt they'd be part of LilyPond yet.

Can you give us Rietveld issue numbers?
