I absolutely agree that we need to do this.  (See my blog post [1]  
from February and the follow-up e-mail conversation [2] on how I think  
we should go about it.)

Given that the goal of the Plone 4 release is to incorporate fairly  
low-risk things that have already been built, though, I'm not sure  
this is an appropriate goal for Plone 4.  And while I agree that in  
the end view templates should be browser views, I don't want to make  
that switch until we have a complete TTW editing story for browser  
views.

I think this is the point you were making as well.  If we start  
actually working on this and make rapid progress, and have a solid  
migration story, I'm willing to reconsider for Plone 4.
