> While in our interpretation the RFCs do not require CNAMEs to appear in any particular order, it’s clear that at least some widely-deployed DNS clients rely on it. As some systems using these clients might be updated infrequently, or never updated at all, we believe it’s best to require CNAME records to appear in-order before any other records.

That's the only reasonable conclusion, really.

And I'm glad they came to it. Even if everyone else is wrong (I'm not saying they are) sometimes you just have to play along.
