So basically the entire premise of the article, that

> existing practice today is that 301, 303, and 307 are used correctly pretty much everywhere

is flat out wrong. I guess that's a nicer and more probable resolution than "standards people suck!".

From the rest of the article, I can only assume it means 'correctly' in the sense of the reality arrived at by both user agents and servers after years of standards-flouting, which is now 'correct' if unspecified behavior.
