My coworker Albertas recently implemented something like this in
SchoolTool (I've CCed him).  Unfortunately it turned out to have some
unforeseen consequences, for example, request.URL does not contain the
path elements you "eat" manually, breaking self-posting forms (those
that use <form tal:attributes="action request/URL">) and our login
mechanism.

I would also like to know that.
