Sorry, no, it isn't, especially in the context of at the same time suggesting
that everyone should start using the most recent stable release immediately
(instead of, say, selectively picking security patches).

I don't think Tegra users would be happy if their audio stopped working,
and it seems unlikely that they would accept the argument that they should
be happy to be bug-compatible with the latest upstream kernel - even more so
if that latest upstream kernel is a release candidate and the problem was
introduced in the commit window.
