The dist-bound conditional should be specified outside the spec file,
preferably on a distribution-level. E.g. RHEL decides that it does not
want to distribute a documentation, then it defines "%_without_docs 1" in srpm
build root macros.
This way the package becomes fully agnostic of the distribution it builds in.
No hard-coded exceptions anymore.
That may work fine for distro based decisions but 100% of the distro based conditionals I use are to work around package dependency versioning or availability, which that wouldn't solve.
Thanks,
