This is a very important point. We've had some discussions during the Plasma 
sprint (which I'm currently attending), and "make it a Framework" was offered 
as a solution to scope some libraries. While I think that should in principle 
be possible, separate libraries do not automatically become frameworks.

The fact that they're split and less interdependent makes it easier to have a 
bigger set of libraries, but it's really important that we only ship libraries 
that satisfy a certain set of qualities, such as API and ABI stability, 
complete documentation, unit-testing, etc. Otherwise, our newly created 
"Frameworks brand" will quickly lose its meaning and value, and worse, devalue 
other, high-quality libraries' reputations. Strong requirements are a good 
thing here.
