Yes.  The guitar fretboards concern a whole family of instruments
literally millions of people play.

Your extension makes only very limited sense for scores reproducing the
"original breaks" of a single canonical original document.  That's a
rather specific situation.  If the breaks in _one_ version of a score
are so important, why is that the _only_ conceivable version of the
score with relevant breaks?  And if that is the only conceivable
version, why would we put the breaks in conditionally?  If they are
disabled, we could be producing _another_ document with breaks that
nobody should ever want to reproduce.
