Thus said David Levine on Thu, 13 Oct 2016 16:16:38 -0400:
"X-" headers are deprecated by RFC 6648. We could add, say, a Mailer
header.
While the RFC does say this:
3. SHOULD NOT prefix their parameter names with "X-" or similar
constructs.
Why? What's wrong with "X-"? If the intent of RFC 6648 is to do away
with any special interpretation of "X-" in headers, then why make such a
statement thus giving a new special interpretation of "X-"? Shouldn't
"X-" be just as useable as any other prefix in a header post-RFC6648?
Thanks,
Andy
