The flaw in this logic is assuming that this is something that resulted
specifically from this draft, or that is a problem the RFC should be
able to solve. A tag "sr-Latn" or "sr-Latn-CS" could be registered under
RFC 3066; in fact, the former is registered, and there's a reasonable
likelihood that the latter would be apart from the proposed revision.
Under RFC 3066, a site admin could already change the way the site's
pages are tagged, leading to a change in user experience. That problem
cannot be attributed to the proposed revision.
