I would move the last sentence to a separate paragraph. I don't like
to read in the specifics that an implementation is likely to cause
interoperability problems... At least, say "Legacy 8-bit encodings...".

As for the first sentence, is there a simpler way to assess that in 
future other encodings may be standardises? I am confident "Until such 
time as" is good English, but I find it difficult to understand it.

Could you state that if it decides to pass it it must do it verbatim?
Otherwise some implementation could choose to "rectify" the non-standard
header value, and this would be a Very Bad Thing.

ciao, .mau.
