Targeting API 23 or later means you must request dangerous permissions at runtime. The warning is staying that this is a one way switch: there is no way to revert back to targeting API 22 or earlier once you make the switch to the runtime permission model. The Dev Console is just confirming that you do indeed want to make the permanent switch.
