I believe you missed that disallowing “Quantum Recovery” is required in order to allow a majority of coins to be recovered by their rightful owners! We can allow people to spend funds if they can prove that they were built using a seedphrase and they know the seedphrase, but this only works if vulnerable spend paths are prevented!

There is no "source" other than this conversation - it's all theoretical.
I'd agree with your conclusion, but it's moot. A cyptographically relevant quantum computer is physically impossible.
You should present your proof of this claim to the world so that we can save countless time and resources.
