--- Comment #3 from Jakub Jelen <jjelen at redhat.com> ---
After the years, I do no longer thing this is a very useful thing to
do. This would work nicely with RSA keys, but not with ECDSA, where the
public part is not always available in the private key object.
Additionally the need to login for most of the private keys makes its
use more complicated.

Moreover, all the sane smart cards have at least the public and private
keys available. Having only private ones I would consider a
misconfiguration. I am sorry for the confusion.
