It is currently the standard. While work on OTS3 continues, until it has an effective means of installation for the masses it will not be accepted. I have to be honest...I haven't even looked at OTS3 since the fight over what a theme should be...but if you can't quickly and easily port over what I have...Im not starting over. Backwards compatability is part of any new standard and from what I am reading here, it was not addressed.
