First the context, we are speaking of srpms.

Use case: you want to test a pre-version of R before it is released and you 
want to do it using dnf while not having to de-install the current version, 
with all its libraries.

Since the purpose is both to install and test both r-devel and the rpm 
packages the goal should be that the spec file should be as close as possible 
to the final spec file.

What I am saying is that by experience it is easier to test and adapt a spec 
file if only a small number of conditionals are needed to use the current spec 
file.
As far as I remember, from Miro's messages in fedora-devel, that is what is 
being done in the python packages.
That is also what I have done for other packages, although not a language, 
like lyx.

I hope that now it makes sense,
