\accidentalStyle is not about figuring out what the best way of
typesetting things are, but about specifying one way to do it.

So the threshold for a feature is more like "are people going to have a
reason for wanting it" rather than "is it the best way to typeset this".

Of course, we will save ourselves a lot of discussions if "are people
going to have a reason for wanting it" does not imply "we need to
provide an implementation for exactly what they are going to want" but
if it is reasonably easy to make LilyPond do what you want without your
particular use case needing to be coded into LilyPond in some manner.

Late to the conversation, but watched everything from afar.

So, I went into the file scm/music-functions.scm as well and basically copied the alist entry for piano:

;; Stone's suggestions for accidentals on grand staff.

;; Accidentals are canceled across the staves

;; in the same grand staff as well

(piano #f

(Staff ,(make-accidental-rule 'same-octave 0)

,(make-accidental-rule 'any-octave 0)

,(make-accidental-rule 'same-octave 1)

GrandStaff

,(make-accidental-rule 'any-octave 0)

,(make-accidental-rule 'same-octave 1))

()

GrandStaff)

and I figured that adding another entry like the following would make it possible:

;; Similar to the piano style, accidentals are canceled

;; across the staves in the same choir staff as well

(choral #f

(Staff ,(make-accidental-rule 'same-octave 0)

,(make-accidental-rule 'any-octave 0)

,(make-accidental-rule 'same-octave 1)

ChoirStaff

,(make-accidental-rule 'any-octave 0)

,(make-accidental-rule 'same-octave 1))

()

ChoirStaff)

But that didn't change anything when I tried

\accidentalStyle choral

\accidentalStyle ChoirStaff.choral

or any other combination. What am I missing?
