Ha, you uncovered a bug in \frac, it should be (in core-mat.tex). I
didn't count the braces right when I added the \mathematics macro.
Stupid error. 

\def\frac#1#2%
  {\relax\mathematics{{{\mathstyle{#1}}\over{\mathstyle{#2}}}}}

Concerning the italic, it's what you asked for -)

  \let\mathop\normalmathop

gives you non adapting math. I can make a \setupmath command ...
