I know that you can objectModel.get(HttpEnvironment.HTTP_REQUEST_OBJECT)
but that only solves passing requests/responses/cookies into library
methods. But when methods return/extend HttpServletRequest (etc.) I can't
do the following in my XSPs or logicsheets:
<xsp:logic>
  request = new SuperRequest(request);
  //or
  request = UberHttpLib.getUberRequest(request);
</xsp:logic>

if the SuperRequest extends HttpServletRequest
or the getUberRequest returns HttpServletRequest.
