No, the x- prefix was originally intended to separate values that
will never be sent by compliant Internet hosts from those that will,
such that people using the same namespace inside software or internal
networks can use x-names without worrying about future conflicts.
It is not for experiments, proposals, ideas, and especially not
for standards.

I have no idea why people keep trying to use them in protocols.
No software should ever be deployed that uses an x-prefix outside
of its own internal communication.
