While that is the "correct" policy, I would argue that a
fully-backward-compatible extension like this would be a sensible
extension, at least until we establish a track record with the new
"time-based" release policy.

If necessary, we could implement it in the same way that Five did for
Zope 2.7, by creating a product which does a controlled monkey-patch for
the 2.8 (or even 2.7) releases, and then incorporating that product,
minus the monkey patch, for 2.9.

Ah, yes, I should read the whole message first. ;)

+1 for the "product-includes/*" directory notion, by the way.
