Scope of svn_auth_baton_t and providers?

From: <jerenkrantz_at_apache.org>

svn_auth.h has:

/** Initialize an authentication system.
 *
 * Return an authentication object in @a *auth_baton (allocated in @a
 * pool) that represents a particular instance of the svn
 * authentication system. @a *auth_baton will remember @a pool, and
 * use it to store registered providers.
 */
svn_error_t * svn_auth_open(svn_auth_baton_t **auth_baton,
                            apr_pool_t *pool);

/** Register an authentication provider.
 *
 * Register an authentication provider (defined by @a vtable and @a
 * provider_baton) with @a auth_baton, in the order specified by
 * @a order. Use @a pool for any temporary allocation.
 */
svn_error_t * svn_auth_register_provider(svn_auth_baton_t *auth_baton,
                                         int order,
                                         const svn_auth_provider_t
*vtable,
                                         void *provider_baton,
                                         apr_pool_t *pool);

--/--

This means that a provider is only within the scope of a particular
baton. This troubles me as I wonder the interaction of the
registration here. If we have a DSO that provides an authentication
provider, how do we register it? Do we require explicit
fore-knowledge of authentication providers in a client (i.e. the
client explicitly calls register provider for all the providers it
knows it will have - i.e. what we do in
subversion/libsvn_ra/ra_loader.c)?

To me, that seems a bit constraining. I guess I'd rather see auth
providers have the ability to register themselves. My goal would be
to have a 'special' directory where I can throw in new auth
providers. (I'd also like to do this for ra's, but it's too late for
that, I think.)

How do you see such a model working with this scheme where multiple
auth batons can co-exist simultaneously each with different
providers? Or, are we forced to hard-code known auth providers? --
