The right list would be devel at . Long ago we used to have the ghc etc srpm 
macros in redhat-rpm-config, they were changing quite often, as arches were 
added or removed and it was decided to split them out.   I do not have a 
strong opinion either way. we just need to ensure that they are available at 
srpm creation time, and adding a bunch of packages to the group that we try to 
keep minimal seems wrong.

Most languages have macros for building binary rpms in different rpms that 
they BuildRequire, the srpm macros are purely for things that need to be 
defined in the buildroot when we build the srpm. Since we can not add them as 
a BuildRequires we have to make sure they are there.

What we probably should do is add a bootstrap macro and enable all the 
different srpm Requires to be dropped for bootstrapping purposes.
