What more could we possibly want!! lift comes from balanced action/reaction.
Momentum is just book keeping.

Regardless of how one feels lift to be created, centripetal accelleration exists were flow turns. Fluid static pressure is changed as the fluid mass inertia resists (reacts) to that acceleration. Since, on the wing, that acceleration is normal to each surface element the pressure lift contribution is equal to the vertical component of the that mass acceleration. When all is summed up the lift is equal to the vertical comonent of the total mass acceleration in turnig.

What happens aft of the TE is not basic to creating lift.
