Fortunately it is was not hard at all, it took me one hour to find where 
to tweak, do it and test it under 2.8.
And it took *that long* because it was my first excursion under Zope 
skirts ;o)

Namely, it required three small additions to Extensions.py, 
zopeschema.xml, and zope.conf.
You can see details below, but that version was coded against 2.8 cvs 
snapshot.

I believe it will remain mostly the same against 2.7.5, but is better to 
be safe than sorry.
So I'll test it and re-submit to collector as Andreas suggested 
previously in this thread,
but this time I'll give it a higher priority since it seems to be useful 
and easy to add.
 
cheers,
