There are 2 cases:
(1) your software understands the X- name. In that case you can make it
understand the name without the X- easily.
(2) your software does not understand the X-name. Then, if the name becomes
standardised, you have to change it anyway.

Of course, if you are using someone else's software, you are stuck... until
they change it. But that is better than having REL="cheese" appear with
a meaning that all ftp links in the current document are to be interpreted
as http: links, and you having no way even to guess about it.

We need to encourage standards-based behaviour.
If experimentation is permitted at all -- and in the IETF world it has to be
permitted -- it must be clear what is experimental and what isn't.

So I think X-cheese is OK.
