As I said above, my main concern is keeping publisher events and
exception views intact. Some of these events need to happen in code
that's currently inside repoze.* middleware. Like "before transaction
commit", "publication failure" or "publication success". For exception
handling Plone wants to load some settings from inside the database.
Mangling those into a WSGI environment is a bit tedious - having a
real Zope request/response object makes that a bit easier.
