No. This IS a test, as the news specifically says.
If feedback is overwhelmingly negative with all players across all platforms, then it won’t go ahead past the test period.
If feedback is only that a few specific maps need adjustments or restrictions, then there’s a high chance this will happen.
If feedback is that a large chunk of players are enjoying it, then it probably stays (though I still expect some maps to need adjustments to help their playability in high BR, as many have already commented).
And so on.
Gameplay & map developers are actively watching for this purpose to help decide what to do.
