That's fair.  I do agree that being able to get the underlying CA type
might be necessary (as in this case), and the native CA type should
certainly be available to anyone who wants to use it.   I am
definitely not opposed to a wrapper that is "thin, complete", I just
think it's not enough.  And I think that most (and perhaps all) of the
extras I've come to rely on can be layered on top of a thin wrapper.
