So did kdelibs4.

Against asking? Oo

Except that frameworks derive from the same code base, are made by the
same people and powers the continuations of previously seen kdelibs4

There is a need for bugfixes, which unfortunately may or may not
contain features. That being said, with frameworks being mostly
libraries a 'feature' is a new function, which quite simply can not
break existing functions by being there. C++ doesn't work like this.
