Quantum resistance on BC2

Is there any discussion or development around adding quantum-resistant protection to BC2?

I know this is not an immediate problem and probably won’t become a real concern for decades, but implementing quantum protection early could become a huge advantage for the network. It would prevent the creation of vulnerable wallets from the very beginning.

This is something that could become a major issue for original Bitcoin in the future, because many old wallets are already lost and will never be migrated if the network eventually upgrades to quantum-resistant cryptography. That could leave abandoned wallets, and potentially even Satoshi’s wallets, vulnerable to being stolen by quantum attacks.

I believe having quantum resistance built into BC2 early on would be a massive differentiator and also a very strong marketing advantage for the network.
