We've broken the admin apps in pretty much every single release. And
they generally don't complain. If someone developing an admin app
hasn't been doing extensive testing starting *at the latest* with
beta1 (and recommended per each alpha), they shouldn't expect to
release until quite long after the release.
That said, a stable set of system views certainly wouldn't hurt - but
making extra noise about a simple change like this one would likely
not make a difference.
