The plan is to incorporate the changes specified in the PRI #367 background document into CLDR v33 (ca. March 2018), and to work thereafter to improve the tooling for the new specification, and streamline the process for submitting new keyboards into CLDR.
The committee is soliciting feedback on the proposal so that it can make any necessary improvements. The closing date for providing feedback is February 1, 2018.
Please see the PRI #367 page for complete details.
