we rewrote the checklist deleting any reference to 'threshold' or 'reference' speeds, deleting any 'add 5 knots' or 'add 1/3 of the wind' nonsense - and never had another damaged nosewheel or heavy landing ever again.

I am Gobsmacked I hope you also wrote "not to be flown in windy condtions", using that checklist.
What relevance does your approach speed have to your touchdown speed anyway?
Why if you are carrying plus 30 kts above your ref speed on approach does that mean you are doing so at the threshold?
The 'gust factor' addition is only relevant to large aircraft (such as airliners) with high inertia which do not react to gusts as quickly as light, low inertia aircraft such as your Cub.
New to me. In a windshear are light aircraft immune to sudden and abrupt sink? How do you counteract that with not enough airspeed over the stall?
