I'm not an expert in what hinting is, but at least for the music
typesetting, I don't think it would make any difference, since
Lilypond determines the exact position of each symbol. It might
make a difference if the symbols are used within ordinary text, 
where TeX handles the positioning.

You mean that the proportions are different for different font sizes?
At least for the few symbols I've designed for the Feta font, this
hasn't been done in any systematic way.
