I guess you could try to plug in Zope 3 TALES into Zope 2 page 
templates.. :)

But backwards compatibility with Zope 2 (while not *breaking* 
compatibility with Zope 3) is in my mind more important than supporting 
Zope 3 features per se. So that would mean it's more important to me to 
be able to write Zope2/Five code that can be ported to Zope 3 than to 
write Zope 3 code that can be ported to Zope2/Five.

If they're that subtle we'd better not bother with them. :)

I'd prefer not having a global configuration for this, as then you 
couldn't run mix Five code that has different assumptions. The 
alternative is configuration per statement or per ZCML file, but that is 
not really preferred either.

I'd rather just bite the bullet and make Zope 2 page templates work. 
Zope 2 eventually will make Zope 3 page templates work anyway, and then 
we're fine with Five. :)
