It's five year old thread. With G+B fail 15° pitch limit during a GA it just that, during a GA. And it's for the pilot to ensure that. Aircraft is in Direct Law there are simply no protections. With only half elevator available precise pitch control is difficult more so at approach speeds. That's why even in approach the gear is lowered at 200kts. For Neo the reference speeds are lower than CEO because in A320
VLS= k×Vs1g with 1.23 ≤ k ≤1.28 and VLS ≥ VMCLSharklets reduce VS1g but the the bigger engine increases the VMCL. So if you see Vref it's 5kts less that CEO till 116kts then remain constant. CEO Flap3 speed are higher than Vref by about 5kts but in Neo they are higher by 10kts making Flap3 speeds same. This is possibly for better tail clearance. G+Y full elevator control is available so no pitch restrictions are imposed in a GA.
