That is not very interesting, since I would need to maintain the 
%{fedora} < 21 branch anyway and the results on F20 and F21 could differ.

So I have different question, related to building SRPM. Is it possible 
to detect, that this is just SRPM build task? The macros are not needed 
to evaluate to build SRPM, so I could just ignore the %{load:...} by 
some condition.

Thank you for implementing it :)
