Actually I remember the discussion on this. All "regen to a stop" in EVs actually consume power at the lowest rpm. Tesla can theoretically do it if they want it to, nothing to do with the motor type.
Regen braking to stop? (similar to BMW i3)
Is there any definitive proof that the Bolt and BMW consume power when coming to a full stop without the user applying brakes? I read a bunch of speculation, but no one who actually knew anything chimed in.
