I take the liberty to add my 2 cts.

It's a great advantage having dropped GUB (which produced the
installers) it was a maintaining nightmare.

Though, I miss the installer, too.
The installer put several scripts in my bin-folder pointing to entries
of /lilypond/bin (I'm on Linux, lilypond 2.23.9 for now):
abc2ly  convert-ly  etf2ly  lilypond  lilymidi  lilypond-book
lilypond-invoke-editor  lilysong  midi2ly  musicxml2ly
They worked out of the box.

With current archive I need to care myself, i.e. invoking above with
correct pathes or creating scripts myself.

So, I understand both sides ....
