> As we can see lots of TODOs for region replica feature in the
> AssignmentManager' code. And also, now we rely on the openSeqNum to determine
> whether a region has been successfully reopened, but the openSeqNum for a
> non-default replica region seems unstable...
> It is too late for the 2.1.0 release so let's just add a note in ref guide to
> say that region replica does not work well with AMv2 first, and then start to
> make it stable in follow on minor or major release lines.
