--- Comment #4 from Fabio Valentini decathorpe@gmail.com --- This is well-intentioned, but will not work, and will produce packages with broken dependencies.
Our tooling (mostly because of limitations in RPM and pungi) will still include noarch packages in repositories for all architectures, even if they're explicitly excluded on some of them (because ExcludeArch / ExclusiveArch headers are only included in SRPM files, apparently).
This is why I explicitly said to either remove those features for all architectures, or to drop ppc64le and s390x support for the whole package.
