Right.  Or for SSH.  For example the Belgian EID card (a pkcs#15 card)
can be used for SSH.

Actually we did the OpenPGP smardcard specification with the goal to
habe one and only one smardcard application for GPG.  This simplifies
the code and makes it possible to test cards from other vendors.  Thus
if a smardcard vendors wants to support OpenPGP via GPG they need to
implement the OpenPGP card specification in addition to what they
already provide with their card.  This can be implemented as a
different view on the card's data objects and functions and would need
only minimal extra code.
