I think your logic is flawed- modern turbo jets spool up very quickly especialy at approach thrust and have much more excess thrust to get away from tbe shear besides the fact that the lower penetration speed of light aircraft makes them more prone to windshear effects.

Small, general aviation aircraft are much more prone to the effects of low-level wind shear than large commercial aircraft because their approach speeds are much closer to their stall speeds.
Having practiced windshear recovery in several jet sims including the Airbus I can assure you there is no way a light aircraft would have got through the same equivalent shear
