That sounds to me like a reasonable approach.  Rather than messing with
feta-autometric, you can define your own feta-flag-autometric.

I think that's reasonable.  feta-noteheads was already separated because of
hitting the 256 glyph limit when we added shape noteheads in multiple
styles.

I think that what causes problems is you lose the definition of
black-notehead-width (which comes from feta-noteheads).

Great!
