Aha, I see; I am thinking too TeX-like;
the vertical-align:bottom just says the numerator should align
it's bottom to the baseline of it's siblings (but has none),
but it's baseline is unchanged.
Hmmm...

In one sense, simpler doesn't matter where authors seldom if ever have
to write the rules for mathml fractions. But on the other hand, simpler
means it's more likely to actually work :>
I'll look further into this...
