I agree. 6/8 communicates precisely six eighth notes--nothing more,
nothing less. While 2/4. might be a common conventional feel, it is not
a hard-and-fast rule.
And correct me if I am wrong, but the problem you stated about 20 not
being a duration (as Lilypond defines it) is that it is not a *singular*
duration. For instance, all of these durations have the same length
(moment) of 1/20:
1*1/20
4.*2/15
16*4/5
Writing "\time 8/20" leaves one wondering how that /20 should be
rendered if not as a simple number.
Writing "\time \musicFraction 8 \tuplet 5/4 { 16 }" lets the composer be
explicit about the intention.
