Just imagine a piece (say, a waltz by Johann Strauss[*]) that has not
a single segno, but a bunch of them. It might confuse an orchestra if
the conductor asks to start 'at the segno' during a rehearsal – from
experience I can tell you that at least one musician will ask 'which
one?'…
Then that score is not an example of using a segno and a rehearsal mark at the
same point.
It is an example of ambiguous segni, and stacking rehearsal marks on top of
them addresses only half of the issue: the D.S. instructions remain ambiguous.
In other words, it actually does make sense to have both rehearsal
marks and segno signs at the same position.
Between preparing caesura-related MRs, I will try allowing a rehearsal mark to
occur at the same point as the other types of marks. Maybe now, after having
spent some time away from it, I will see other ways to do the things that made
me implement the restriction in the first place.
I would like advice on whether it would be ideal to split Mark_engraver into
Rehearsal_mark_engraver and Performance_mark_engraver.
