How about splitting up the patch into backend (i.e. supporting the spanner-
type and -text property of the crescendo event in the engraver) and frontend 
(the new definition of the \cresc command). I'd really like to get the 
functionality into lilypond (i.e. the backend), since I'm currently preparing 
Urtext editions with lots of "cresc." (http://www.eybler-edition.org/). 

That way, one can always define one's own \mycresc function that creates a 
crescendo event with the corresponding properties set, while the \cresc 
command still shows the old inconsistent behavior.

Yes, anything that requires manual changes (or even automated changes) is a 
real PITA if you are seriously working on larger music editions.

I don't mind that much, it just that I rely on properly working text crescendo 
syntax locally, so I would probably not do much lilypond development if I 
needed to keep the patch locally... I would be exclusively running my own 
branch, so any patch to master would require quite a lot of work.

Cheers,
Reinhold
