\sin etc should not behave like \text{...}. \text should adapt to the
surrounding style while \mathoptext should not. In particular, in the
following

{\ss $\sin x$}
{\bf $\sin x$}

\sin should be in normal text upright font and not adapted to the surrounded
text.

Is it possible to set a value of functionstyle so that the surrounding text font
styles are ignored (but the font size is not).

I realize that this takes us back to the old 'bold-math-in-section-heads'
debate. With the current implementation:

\section{$\sin x$}
