Breaking RSA is now a more real threat than ever!

The importance of hybrid and PQC solutions from DIDs and VCs is extremely
pressing. I know there is some work on post quantum signature type
<https://www.ietf.org/archive/id/draft-prorock-cose-post-quantum-signatures-01.txt>.
Is anyone else working on similar systems?
