Today some user on IRC noted that there were some doubts about if developers are allowed to stabilize packages they maintain when they are able to test on relevant arches (I guess this would benefit amd64 and x86 mostly as it's likely more spread).
If I don't misremember amd64 team allows that, but looks like devmanual doesn't reflect that yet: http://devmanual.gentoo.org/ebuild-writing/ebuild-maintenance/ Then, I guess we would need a confirmation to fix devmanual and, in advance, know more about if there is any other arch team allowing it (x86?) Of course, developers stabilizing packages should still follow the usual test procedures as arch teams members will do. Thanks a lot
