No. Consider



\section{$\sin^2 x$}

{\ss $\sin^2 x$}

{\bf $\sin x$}

{\it $\sin x$}

   f = \sin i\omega x


1. The default should be \mathupright (old behavior)

2. The user should have the option to change the font to \normalrm, 
\normalss (or \normalrmbf and \normalssbf for titles).

In both cases, the style should not be affected by surrounding styles.
