"Yes. Incorrectly implementing the HTTP spec is widespread though"
Huh??? First of all, that's a pretty serious statement to be making with no evidence to support it. Plus, that is no excuse for any server that is NOT compliant.
The very fact that nginx decides to create HTTP status codes, willy-nilly, for its own use shows at least the suspicion that strict compliance is not a priority for them. Thankfully, it is for other web servers.
