We can put it into CVS, we can put -pkg tarballs on the FTP site retrievable via the package UI interface in XEmacs, but it won't go into the Sumo until 21.2 become official. Not quite. We may distribute 21.2-only packages if they are bytecompilable with XEmacs 21.1. If you follow good coding guidelines, your package will be bytecompilable by an XEmacs that does not have the underlying support. See the LDAP package as an excellent example of this.
