You can have your class, and I also see, in average, a good effect of
vertical-align: middle. Added to the stylesheet.
About your #2 in the original message: div.math has a text-align: center
in the default stylesheet.

I agree about the gamma. The -D option's optimal value is questionable,
but I agree that with the default, subscripts of subscripts are too
small. I'll use 110 as a compromise in the defaults :)

Doesn't it already?

It's not Sphinx that has large font, it's you -- Sphinx does not set a
specific font size for text :)
