I hope they'll reconsider and add a few more, even if they are limited to Amn, Swordcoast, Western Heartlands, etc. or something like "Outlander".
Otherwise the outlander background doesn't make much sense. I'd love to play as a barbarian (berserker) or druid, but if I'm forced to have the Baldurian tag that won't happen.
Until they add into character creation that we are forced to be Baldurian, I choose to pretend that tag does not exist. It makes no sense to create a character (and most of us probably come up with a location in the backstory) and then find out later that we can't be who we think we are. And you are absolutely right that it makes no sense for an Outlander background.
