Christian,  See it from a distribution point of view. If we update to KDE 
Frameworks 5.12 (as an example), then we want to have the situation where the 
user would end up with all the correct libraries and not in the situation 
where one framework library is version 5.12 and an another one is version 
5.10, etc.   

Yes, for building the frameworks, the version checks in the CMakeLists.txt 
files could be sufficient if properly maintained. However it would also depend 
on the buildsystem is used by the distribution. Otherwise one could end up 
that a  Tier3 library is build against an older version of a tier1 library and 
afterwards the tier 1 library is updated to a higher version.

So all in all, we as packagers trying to utilize whatever we can to ensure 
that our users are ending up with a consistent set of libraries and programs. 

I can imagine that the current versioning of the Frameworks Libraries are not 
the most ideal ones for the library maintainers themselves, as that a version 
is updated even when there are no changes. But on the other hand this would 
increase the consistency between the libraries themselves.  At least for the 
packagers. 

As Hrvoje indicated a couple of exceptions can be easily handled, but if this 
would turn out that KDE Frameworks 5.12 would consist of libraries with all 
different version numbers, then it would be the greatest nightmare for us 
packagers.
