The industry is mostly pivoting to hybrid schemes, and it's sensible to want a higher-security curve to pair with a higher-security PQ algorithm.

The pivot is occurring on both key agreement and signatures. Hybrid schemes currently only exist for key agreement. Perfect forward secrecy means that as long as the key agreement schemes are secure against Shor’s algorithm, we can afford to do a much more leisurely roll out of PKI with PQ signing algorithms. Whether people will opt for “hybrid” signatures is yet to be seen.
