Hi Adam,
I think you've misunderstood my comment. I don't think that headers 
starting with "X-" should be treated specially. Historically many X-* 
headers got widely deployed, at which point renaming them doesn't really 
work. That why I said "to deprecate X- convention".

If one want to use a new header field, than using something without X- 
might be better.

In this particular case, if X-Purpose is already deployed, it is 
probably Ok to leave it be as is. However if changing to "Purpose" can 
be done at this stage without much backward compatibility problems, than 
that should be done.

Regards,
Alexey

P.S. This is my personal opinion, HTTPBIS WG or email experts might have 
other opinions on the subject. So consensus is yet to be reached.
