I'm willing to discuss it, but I don't think you should open an issue yet.

I try to be conservative because it's easier to relax the rules than to tighten 
them.  I have tried to keep in mind the possibility of creating new features 
where LilyPond uses "the" label at a given point of the piece.  (The jump 
instructions already do some of this.)

Having both a rehearsal mark and a segno seems like an unusual editorial 
choice, where it might make sense to force power users into workarounds so that 
more casual users can benefit from the warning.

Before discussing solutions, what are the details of the use case?

* Is this about true rehearsal marks, or one of the (ahem) creative uses of 
rehearsal marks that are floating around in snippets?  (e.g., fermata, CD track 
number)

* Does the user want the rehearsal mark to appear in addition to or in lieu of 
the segno?

* What does the user expect the automatic jump instruction to say?

* Are these the user's personal preferences, or are there historical examples?
