Would it be considered reasonable to hard-wire a special startup message 
in LilyPond proper if it is being built with Guile2 (or rather: detects 
guile-2 on startup)?

The new Homebrew build uses guile2, and I suggested they turn the 
startup message

GNU LilyPond 2.22.0

into something like

GNU LilyPond 2.22.0 (Guile 2 build)

to aid debugging, and if I understand Jefferson correctly, they do not 
want to touch the source code themselves.
