It is legal latex and it expands the definition of \foo if it exists.
I'm sure this can be very useful, actually :) Here is an example file
to play with:
\documentclass{article}
\begin{document}
\def\foo{bar}
\section{abab}\label{ab\foo}
section is \ref{ab\foo}
\end{document}
But the point you raise is valid: we have to decide somehow whether
the label key should be kept as latex sees it, which can be rather
surprising (\label{a{}b} == \label{ab}) but also useful (\label{foo}),
or if we want to hide latex subtleties under some conversions
routines, which will undoubtedly confuse real latex users.
BTW, somebody has to ensure also that label parsing in mathed is OK in
1.3.0cvs.
