I don't think that is a reasonable characterizaztion: repoze.tm2,
repoze.vhm etc. are stable and mature, but they aren't unmaintained: for
instance, they actually support Python 3.2. Many he repoze.* packages
are in heavy production use for many non-Zope applications.

That could still be a reasonable choice. Another choice would be to just
add an integration point into the publisher which wrapped the middleware
in at startup time, without requiring explicit configuration.
