Eliminating them completely might be hard for some to swallow. (I'm guessing.
If others can confirm one way or the other, please do so.)

Section 4.5 of
http://www.ietf.org/internet-drafts/draft-ietf-ltru-registry-08.txt
currently says:
   Private-use subtags require private agreement between the parties
   that intend to use or exchange language tags that use them and great
   caution SHOULD be used in employing them in content or protocols
   intended for general use.  Private-use subtags are simply useless for
   information exchange without prior arrangement.

Would a stronger version of this (or the following paragraphs address the
concerns?  If so, proposed text would be appreciated.

Randy
