Mainly because that's what all the other IPub* events carry with them.
We discovered this omission implementing plone.caching, which only needs
the response, but it's not all that unlikely that something else may
need the request.
Of course, "something else" could do the same getSite() trick if needed,
or use five.globalrequest.
