At first glance, it sounds good, but I recall us discussing late at the FtF
that the algorithm URIs don't specifically document a key format, but a
particular crypto operation using that format, so I'd be inclined to say no,
at least not for that reason. Obviously if the actual operation(s) are
different, then it's a no-brainer.
