The reason this bug isn't hitting RHEL right now is simply just because the default
RHEL repositories are much smaller - also crucially things like many -devel packages are in a separate repository.
RHEL actually is hitting this issue in different contexts for an entirely different reason (a bug that caused changelog metadata to inflate over time).

It is in the progress of being fixed.
