I've had in mind creating a problem page on how to design a PQ TR commitment in each key so that if QC were to become a reality we could softfork to enable that spend (and disable normal key path spends): https://github.com/bitcoin-problems/bitcoin-problems.github.io/issues/4 Becoming the author/maintainer of this problem is as simple as making a PR to the repo. The problem doesn't have to be focused on a TR solution but could be a general description of the problem with that and others as a potential solution direction.
