5.c. Stabilizing ebuilds Only architecture maintainers for a given architecture should mark packages as stable on that architecture. The maintainer of the package should always be contacted just incase there are reasons not to do so. The exception to this is if you have access to an x86 machine, in which case you may mark the package stable on x86 if you deem it to be appropriate; or if you are part of an architecture team, in which case you may mark the package stable for that architecture. If you are not part of an architecture team, you should consult the guidelines below; if the architecture you are looking for is not listed then please consult the relevant lead. So the x86 exception should be removed.
