For the record, I agree with the points made by Roy, and don't believe
normative text of any kind is appropriate here at this point in time.

I could live with something like this in HTTPbis;

"Some HTTP clients intentionally ignore the authoritative media type
of some messages and instead 'sniff' the representation to determine
the effective type.  For Web browsers in particular, work is ongoing
to document a sniffing algorithm[non-normative ref] that reflects
common practice amoung popular implementations."
