But if you try and do \key d \bayati you'll get that error.

That's nice. But the documentation clearly says "To create
non-standard key signatures, set this property directly."
Surprisingly enough an undocumented alternative doesn't work.

You haven't said it was a feature before. Why do you say it's a feature now?
One interesting thing is that if I make the key signature
\set Staff.keySignature = #`(
(2 . ,HALFFLAT)
((0 . 6) . ,FLAT))
then a spurious flat gets added instead of a spurious half-flat. And
if I set the half-flat to actually be a half-flat, the spurious
accidentals still get added. And even if I change the half-flat to be
a full-flat, the spurious accidentals are still added. So are you
sure this is a bug to do with the sixth-tones?
