These are bad ideas, because people *WILL* do the absolute minimum
and as such will end up breaking non-tier1 platforms even more
often than they do already.
People need to remember that maintainers of non-tier1 platforms
spend most of their time fixing problems that can easily be dealt
with by the 300+ developers not worrying about non-tier1 (as it
hardly ever requires in-depth knowledge of the platform). For the
non-tier1 maintainers this is a *BIG* waste of their time...
