Me too 8-(

IMO this registration should be provisional, not permanent, because it
doesn't meet the requirements of sec 2.1 of RFC 4395;

   The use and deployment of new URI schemes in the Internet
   infrastructure is costly; some parts of URI processing may be
   scheme-dependent, and deployed software already processes URIs of
   well-known schemes.  Introducing a new URI scheme may require
   additional software, not only for client software and user agents but
   also in additional parts of the network infrastructure (gateways,
   proxies, caches) [11].  URI schemes constitute a single, global
   namespace; it is desirable to avoid contention over use of short,
   mnemonic scheme names.  For these reasons, the unbounded registration
   of new schemes is harmful.  New URI schemes SHOULD have clear utility
   to the broad Internet community, beyond that available with already
   registered URI schemes.
