The single subkey isn't usable without the primary key (or rather, the
primary key minus the secret parts of the key) attached, so exporting
just a subkey won't really be helpful.  One way to do it would be to
export the key with all subkeys and then --edit-key and "delkey" the
subkeys you don't want.

That's the way it works now.
