It is still not the common case. While people indeed want the ability to 
override presentation, *most the time* this doesn't happen, because it's 
too much work and isn't necessary. The point is not whether people want 
to do it, but whether people will do it for most packages, and whether a 
browser_foo setup will support/encourage any of this better than the 
alternatives, and whether going that way won't make some other things 
harder.

I think we all agree that we shouldn't separate views from presentation 
too distantly; we've learned our lesson there. We also noticed nobody 
was exploiting our separation. So now while we're going to put them 
together we're still hoping some unconventional structure will magically 
be more supportive of this than the alternative, which is simply putting 
them in the same package. The only way we're going to encourage people 
to split separation from content is by making that very easy to do. I 
thought we've figured that pacakage-structural encouragement was only of 
minimal use.
