Prevent partial yield from happening
In the current example / reference pipelines it may happen that only one architecture is released through the yield job since they only need(s)
the same architecture check jobs to run. I'd argue that usually (by default) you don't want to yield architectures independent because your versioning in rpm-ostree depends on the commits and pipelines that run on those commits. Therefore it'd be cleaner to break off at the yield stage if previous stages fail. Otherwise you could get into inconsistent stages with differing updates / file system states on a per architecture basis
