Ah, I think I now see where your confusion lies.
The time signatures 8/20 and 9/8 *do* function identically:
— the bottom number identifies the duration, *expressed as a fraction of a
whole number*, that should be considered the functional division of the measure;
— the top number identifies how many functional divisions are required to fill
a complete measure.
*By convention*, traditional classical music groups the 9
one-eighth-of-a-whole-note events into three groups of three each, leading
people to say that the duration of a “beat” is equal (in that case) to three
eighth notes.
The time signature “9/8” does *not* (as you imply) actually convey *any*
information about the number of “beats” — the *convention* does that.

Correct. That’s left up to beat-structure et al. — which is, I assume, why that
portion of the time management code exists…?

I suppose Carl and my surprise (revelation?) is that Lilypond has *never*
handled time signatures correctly (where “correct” means “according to the
accepted definition of 'time signature'”).
