Precisely: it is unrelated hence the importance of not using a convention 
that is already familiar to many as a vendor extension mechanism. In other
words, the main argument given for using x- at the time it was proposed was
that it looked like the IETF's X-. Given that this use-case is unrelated and
the IETF is phasing out X- I find the risk of confusion wholly unnecessary.
It's not like there is a shortage of other options.
