It is actually the correct way to do this, and I have
implemented this change.

This is hopefully fixed now.
Chris Gray had the idea to have arbitrary blocks turned in LaTeX
environments and HTML divs. These three new hooks allow
implementation has an add-on rather than a patch.

These problems were caused by a regular expression for
matching latex macros with arguments, that did not allow any
newlines. Now we have a much better regexp, that even
allows for three levels of nested braces.
Time stamps in LaTeX export now also honor custom time stamp formats.
Furthermore, the new option `org-export-latex-timestamp-markup' can
specify special markup for time stamps.
