Yes, I've thought about that as well, but there are two reasons I didn't
do it that way.  First, multiple backward searches reaching up to the
beginning of the document might be slow for large LaTeX documents, and
second, I'm not sure that there are no things like

  \begin{foo}[label=ding]
    \begin{bar}[label=dong]
    ...
    \end{bar}
  \end{foo}

where "ding" is no reftex label but "dong" is.
