Could this be easily fixed by adding macros to EL that would only run when appropriate? Staying with your earlier example:

%post
%{?epel_update_gtk_icon_cache}

 
* Rich dependencies are not supported by el6/el7 RPM and YUM, so anyone who
wants to use them need to have same conditionals.

This can get messy when there are a lot of them, most in my experience with at least end user apps, you rarely need them so the occasional:

%if 0%{?fedora}
Recommends: ...
%else
Requires: ...
%endif

does not hurt readability much.

WIth large libraries that are already complicated that's more difficult, but in that case major updates are discouraged within a release and all but banned in EL so there's not much need or advantage to keeping the specs in sync.
