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.
