I love the idea of unifying content sniffing across rendering engines.
So why not actually aim for establishing something like an argeement,
which, for a start, would be implemented in both CFNetwork and WebKit,
where a #define determines if WebKit's or CFNetwork's sniffing is used,
for the sake of running tests, and in the end the Apple ports could
continue using the platform's implementation by default, to keep
guaranteed consistency with other network clients that are not using
WebKit, even if CFNetwork may not be able to use the exact same logic
for whatever reason.
So everyone could benefit from the improvements.
Just my 2 pfennig,
