I don't see that this is a good point of time.

There has been an influx of badly tested changes to the build system and
directory setup and the web pages that has to stabilise and result in a
workable version of LilyPond.  I don't see the point in branching a
"stable" branch if there is so much in a destabilised state: you'd have
to cherry-pick loads of stuff from the unstable branch as it comes in.

Taking a look at Documentation/en/changes.tely, there has not exactly
been a deluge of new features.

At the current point of time, I see far too much focus on destabilising
the code base that I consider a single-person(?) project of making a
reasonably stable branch while the unstable branch is getting pounded on
something that would work well.

While I see little point in making the quality of Guile-2+ support a
showstopper, I don't see that the current pace of revamping the code
base makes branching off a "stable" branch at this point of time a
sensible proposition.  There just would be too much paralleled work in
trying to get "stable" a sensible moniker.  The stable branch tends to
see only rather superficial testing, and a large divergence from master
would make its stability more a matter of wishful thinking than release
