While having these keys could allow someone else to pretend to be their
owner, it can't compromise previously held conversations as these are
not the session keys but those used to encrypt the key transactions
during conversation startup, that's a Diffie-Hellmann exchange and so
far shows no sign of being breakable especially after the event.
Their security is probably better if on a USB stick in your pocket than
on a drive on an easily accessible machine, but of course require
careful treatment and management.
