Why would it need a direct drive? A mid drive can do the same thing they just don't usually since you'd need to gear for it. direct drives are the most efficient at regenerative braking but they aren't the only type.

Freewheel hub would prevent it.

You would need to put the freewheel between the motor and the pedals, and have an always-spinning chain/shaft

Could be done, perhaps, with significant added complexity (and hence maintenance). In practice it is not, to my knowledge there are no mid-mount regenerative system on the market. It is worth noting that mid-mounts are significantly more efficient than hub mount, enough so that even compared to hub mounts with regeneration, mid-mounts have more range for a given battery / wattage. The vast majority of hub mounts also do not implement regeneration.
