Over the last half week, I've implemented very barebones #OpenPGP card support in @minipgp6@floss.social
Support is limited to Ed25519 and X25519 (since that's the intersection of what minipgp supports and what current cards support).
As expected, there is no fundamental obstacle that prevents use of existing OpenPGP card devices with v6 keys.
