That adds a lot of complexity and 'magic' in the system, in my opinion, 
for few gains. Not a bad idea, but, still in my opinion th eincreased
complexity is not worth the trouble.

No, development packages needs to allow for linking, too, and the .so links 
are in the devel packages. So they need to pull in all the dependent
libraries (and it is the issue in case of vtk, since there is a
python-linked library and a qt-linked library pulled in).

And in case headers include other headers, the devel packages are to be
installed too.
