CQL is (a) very incomplete and (b) about to get more so soon (see https://issues.apache.org/jira/browse/CASSANDRA-296).
If anyone wants to step up and say "this is important enough that I'm willing to maintain it," then great, let's talk. Otherwise, we're leaning towards consigning it to svn history where it can await anyone so interested to come along. :) -Jonathan P.S. Note that we are just talking about CQL the query language, not the rest of the CLI.
