You could e.g. have 2 different editions of the same piece, e.g. one Urtext
and one edited version. You could then use the same files, using tag to mark
the differences.
Also, if there would be a command-line option to select/unselect certain tags,
there would be a clear advantage to use tags for extracting parts. E.g.,
lilypond -usetag viola quartet.ly
could extract the viola part. This approach would result in the need of
fewer .ly files.
This is however just an idea that popped up in my mind right now; I haven't
given it a serious thought. Does it sound like a sensible idea to you?
