Maybe to emphasize the important point - if we have to move quickly, disabling insecure spend paths and allowing seedphrase proofs to spend coins is likely to recover substantially more coins than would be burned. Let’s say we wake up tomorrow to a breakthrough and a CRQC is clearly only a few years away now (highly unlikely but who knows). Given the low level of coins which would be able to migrate in time, it seems like seedphrase proofs are a *way* better option than just letting everything be stolen!
It depends so much on the specific scenario though - if it’s been 20 years since wallet started universally using some PQC scheme, the calculus is very different. This is also why it’s important to emphasize that we really can’t decide anything today and it’s up to a market to decide when/if these issues become real.
