New Brave ETH wallet NOTHING to do with storing BAT rewards?

I’ve noticed a (new) Brave crypto wallet, with an icon next to the menu button.
Same wallet shown under Settings.

However Brave BAT rewards are still linked with Uphold.
Is this discrepancy temporary, or a feature?

In short, yes, because it’s two different things.
