Currently there is no plan to move away from 2.1.x as the maintenance branch.  The next long-term maintenance branch may not be until 2.3 or 2.4, but this will be decided in the future.  We definitely do not want to discourage testing and usage of Lustre 2.2 for experienced users that are already expecting to be doing maintenance themselves, but it has not been getting fixes for known issues that are landing on master and 2.1.x.
