I recall a slightly different discussion I was involved in. I remember 
Zope 2 core developers worrying about the inclusion of Five in Zope 2.8; 
they were worried they'd need to maintain its codebase.

The arguments against this were:

* there's a lively development community around Five, don't worry

* Five has a minimal impact on Zope 2; Zope 2 sources itself weren't 
changing.

Both were true. I don't think it was claimed that your development style 
wouldn't be affected, as obviously we hope people will actually *use* 
Five in Zope 2 development.

With Zope 2.9, this story is starting to change, as Zope 3 technology is 
making it deeper into Zope 2. Then again, I think the people who worried 
then have been becoming more familiar with Five since then, so hopefully 
appreciate it more now as a feature, not just as a potential maintenance 
burden.
