Why do you think that the draft shouldn't be changed during LC? 
Moreover, I had some reasons for doing that. firstly, version -09 added 
the section that was not present in -08 and if I added it now, there 
would not be a  possibility to discuss it. Version -10 presented the 
most stable one to reflect all the comments I received during the LC. 
And -11 was prepared as final for IESG review.

I have fully answered all the question form the message you refer to.

That is the issues that would be decided by the implementators.  
Moreover, one code layer may support this technology while others may not.

RFC2616 gives the following definition of token:

token          = 1*<any CHAR except CTLs or separators>
separators     = "(" | ")" | "<" |">" | "@"
                 | "," | ";" | ":" | "\" |<">
                 | "/" | "[" | "]" | "?" | "="
                 | "{" | "}" | SP | HT



And non-visible chars are not allowed in headers. So only VCHARs.
