Good initiative. This could also become an interesting effort touching 
on some current limitations of Zope 3.

Currently, many Zope 3 packages ship with browser views as well as 
non-browser configuration. The non-browser configuration we can 
typically use just fine, but the browser configuration we cannot (with 
some exceptions as widgets) and would prefer to be disabled completely. 
Whenever the non-browser configure.zcml does an include of 
browser/configure.zcml we have a problem.

We can always provide our own configure.zcml that copies all the ZCML. 
This however is a maintenance nightmare in the long run as the 
underlying Zope 3 code and its registrations can change. This might lead 
us in the direction that was discussed previously - selectively being 
able to turn off some registrations. Still, if you had to spell out all 
page registrations manually, we'd still have a new, different 
maintenance nightmare.

Changing the ZCML registrations in Zope 3 so that configure.zcml doesn't 
include browser/configure.zcml and so on will be quite a bit of an 
effort with risks for backwards compatibility.

Ideas?
