--------------------------------------------------------------

Totally agree with what Stack and Matteo said.

As to [~enis]'s question:

bq. 2) if we are also allowing to completely disable this feature (as in the other jira),
will there still be benefit for this?

Big features usually come in with an option to disable it at first. This is a basic idea to
introduce great features with smooth migration paths for users at the beginning, right?

> I was thinking simplifying/improving the region assignments. The first step is to co-locate
the meta and the master as many people agreed on HBASE-5487.
