That's a difference. Jim's *adapter* refactoring will bring us 
a speed up and solves some problems in the adapter registry
implementation. (lookup multiadapter by it's registration tuple).

Your proposal is just a *cosmetic* change which forces us to
change existing projects and like Florent says: We have to 
write additional python classes for just that. I don't buy this 
as really usefull.

Yes, 
Why the hell do I have to write additional python classes for 
each page registration after your refactoring?

I don't by this as a improvment. 

If we do this, I can add the browser:page directive back as 
a high level directive and then the need for write additional
python classes is just a YAGNY like before. Is this really a 
improvment?

Another problem is, that we have mor then 6 projects build
with zope3 up and running. Such a improvment is not nice
and will force us to change more then ~300 existing page 
registrations. 
It's a horror to think about how many python class we have 
to write if we do this simplification!!!

You totaly ignore that Zope3 is not a experimental framework 
now and stability is also a criteria which should recognized.

Please recognize that some people have built applications
with zope3 since more then 2 years now. And respect that
they are not willing to just change everything wich forces 
them to go other ways then before without a real *improvment*.

btw, I don't dislike the refactoring at all, but I just dislike
that we have to update our projects for *this* simplification.
We have at least to provide both way of registration.
Perhaps it's really time to add a higher level directive pool
for such refactorings. Is this a option for you?
