Currently the discussion around how to address the potential risk of a viable quantum computer centers around two primary issues: the quantum-safe signature schemes (or schemes) to integrate for users to migrate to and use if need be, and what (if anything) to do about any coins that remain secured by vulnerable ECC based scripts, specifically should these coins be frozen, and what mechanisms are available to allow legitimate owners to recover those coins if possible without an attacker having the ability to do so.

This second issue is (and always has been) a very socially contentious one, as the common understanding is it is impossible to guarantee with certainty that no user is being left in a position where they are incapable of generating a recovery proof, and therefore are forever prevented from accessing their coins.

My motivation for writing this is to solve this contention (at least partially) in a manner that can hopefully move discussions forward in a productive direction rather than lead to two opposing plans of action eventually colliding in the real world with live implementations of conflicting rules.

The current solution landscape as it stands to my understanding is:
