As far as I can tell from the docs, yes. But I don't know if there is
some hidden option somewhere that allows it?

That would be great!

And while you're at it, maybe also add similar functionality to the
various ornaments like \prall, \mordent, etc.?  Recently I was
transcribing a Haydn sonata, and had to resort to lots of ugly markup
just to get the accidentals to print properly.

And of course the midi didn't work properly (even with \articulate), and
I had to explicitly spell out the notes with \tag #'midi {...} and
\removeWithTag #'midi for the printed score.  Not sure how much you can
do on the midi front, but at least it would simplify things if the
ornament itself can take accidentals. It's at least halfway there. :-)

Yeah, I was also quite surprised to find out that there is apparently no
way to generate ornaments with accidentals without resorting to markup.
Given the classical roots of lilypond, I found this quite unexpected.
