I don't think that is right. It would create a weird mimetype in old
parsers not handling this, and the new magic would apply to that only.
Can't we use a special magic value for this too?
So, something like:
<new magic rules>
If something doesn't support this new feature we will instead add the
new rules, plus get a new __NOMAGIC__ rule which is unlikely to match
