Considering this proposal elsewhere in HTTPbis:

http://lists.w3.org/Archives/Public/ietf-http-wg/2010JulSep/0388.html

By your logic, since user agents (browsers) would need to continue to
support X-Moz and X-Purpose, it would be incorrect to define the
Purpose header and leave it at that, without also providing some
language instructing user agents how to parse X-Moz and X-Purpose, as
they are in fact used in the wild.

I see describing how to parse the obsoleted headers as standardizing
nonconformant (unspecified) syntax.  Just because it was once done this
way, and adopted in more than one browser, isn't relevant to the
definition of a Purpose header.  Quite relevant to browser development,
not relevant to HTTP.
