True. That was just a suggestion. And, one can very well argue that it 
is definitely not the same thing done differently. After all, the 
<browser:page> we know from Zope 3 is the one that is Zope 3 compliant, 
as anyone would expect.

Very true. Still, I'd be laughing if at some point we discover that Zope 
2 ZPTs are a dead-end wrt this or that feature.

Yup.

Really, the only thing that will *not* work with Zope 2 ZPTs are TAL 
namespaces such as context/zope:title or some_url/url:quote. I consider 
them an elegant way of altering TALES traversal and having things like 
that in Zope 3 ZPTs is a good reason for me to keep them. But again, I 
don't have a hard use case like you guys do... (but I would urge you 
guys to consider a solution to support these powerful namespace thingies 
in Five).

Very well then, I'll shut up and shall support Zope 2 ZPTs henceforth.
