Well, I don't like extra interfaces.  I would be quite interested to
know why the posted code actually works, engraving the proper key and
using correct accidentals for it.  Is it because the Ambitus engraver
pulls its signature from the Voice context (where the engraver sits),
while the standard accidental engraver and key signature engraver take
it (unmodified) from the Staff, where it presumably is set by the \key
command?  Then probably per-voice accidentals would cease working.

Maybe it would be possible to just make \override Ambitus #'keySignature
= #'() work as expected.
