If you are referring to the openpgp card opensc driver, it is really far
from being usable. I have reported the issues I had using the FSFE card

Indeed it is, but it is not much more than other security-related
standards (see X.509 and PKIX). Nevertheless, a card or a module needs
not to support the whole standard, it simply needs to implement the few
operations it supports. PKCS #11's design can support proprietary
applications as well as free software.

Most of the smart cards today are supported by the opensc drivers and
the PKCS #11 driver which is LGPLv2.1. In fact PKCS #11 today is used
mainly by free software (NSS is fully using PKCS #11, gnutls uses it for
asymmetric keys, p11-kit provides a PKCS #11 trust module, and
gnome-keyring, openssh, ...). It would be very good to have an open card
such as the openpgp card to integrate seamlessly in all that software.
