I noticed the same thing when I wrote my zopewiki page
but it looks like new-style classes should work now,
judging by this svn log message:

Fix ordering of testSetUp and testTearDown calls, and allow new style
to be used as Layers by explicitly ignoring the object baseclass.

Also, at the time I wrote that page (in July), I wasn't aware of
which would've saved me some trial and error.
That may be the narrative you're looking for?
I'll update the zopewiki page with a reference to that doc.

Looks like that file is shipped with Zope 2.10.0 and 2.9.5,
but it wasn't in 2.9.4.  I haven't been living on the bleeding
edge lately so I didn't see it.
