I am pretty sure the reason why every thing that appears somewhere about the beta says "This is an early beta build and things are likely to change" (or something to that effect) is because we are still in early beta, things are most likely going to change, and just because something is the way it is in the beta right now does not mean it is "basically confirmed". Let the testing go on, and if Blizzard decides to make a change like the one you are speaking about then good for tanking druids and tanking monks alike, if however they decide to change nothing then things will remain the same way they have for the past seven years, completely playable and otherwise unbroken.
It may be something that druids have wanted for a long time, it may be something that only a select amount of druids wanted for a long time, either way if Blizzard thinks that it will change the game and the druid tank playstyle for the better then they WILL do something about it. When that is remains to be seen though .
