Yeah; that's why I'm so hostile to the idea! Mail headers have X-Mailer: but User-Agent: without the X-; and X-Mailing-List: but Posted-To: and List-Id: -- from a user's point of view it's arbitrary which headers have X- and which don't, and very hard to remember.
For me, it comes down to this For the META.yml spec, should anything not expressly allowed be forbidden? If so, then any extension like this has to be explicitly added to the spec. On the positive side, it doesn't leave ambiguity for tools that work with META.yml. Alternatively, if anything not expressly forbidden is allowed, then it's easy to add extensions, but hard to predict what various tools will do with it now or in the future "X-" or "hints" are just a middle ground to isolate the problem.
