oct-git and its sibling project https://crates.io/crates/openpgp-card-ssh-agent are concrete options for OpenPGP card users to explore OpenPGP use without GnuPG, today.

In addition, the #rsop "Stateless OpenPGP" tool (https://crates.io/crates/rsop) also supports using OpenPGP card devices (see https://datatracker.ietf.org/doc/draft-dkg-openpgp-stateless-cli/ for more).
