The contract is between my server code and my client code. Everything
else inbetween should treat it as an opaque data stream. And that is
the actual default for "no content type specified".

It is actually NOT a warning, but logged as a hard error. Which is rather
strange since it doesn't affect the script at all.

It wasn't my idea that this belongs to the spec at all. Anne sort of finished

how it should be".
