Only if the people that would work on this would otherwise work on KDE 
Frameworks.  AFAIK, that's not the case.

I'm not aware of any cases where people wanted a new feature where they 
didn't also say they would forward port it to KDE Frameworks. 
Personally I wouldn't be in favor of accepting a distro patch for 
something that wasn't going to end up upstream.  For this purpose, 
that's got to be frameworks.

I don't think it's a wast of energy to provide useful features to users. 
  It is a mistake to assume that resources in FOSS projects are 
fungible.  Just because people are prevented from working on kdelibs in 
4.8, doesn't mean more resources are available for KDE Frameworks.

kdelibs is already open.  The packagekit/apper change that Kevin 
discussed is in Fedora.  I'm sure Kubuntu will pick it up in order to 
make the latest Apper work.  It's going to happen, the only question is 
how coordinated it's going to be.

I fail to understand it either (I'm not ignorant of the plan, I don't 
need it explained to me, I just don't think the case to not allow people 
willing to work on features in 4.8 is at all compelling).

It's already happening, so the real question is how to minimize the impact.
