Wait, I think you're mixing things up.  I'm not talking about using YANG Library to identify which datastores a module can be accessed in, so much as knowing which datastores are implemented in the first place.  

For instance, assuming the "ephemeral" datastore example example in the draft, a client knows a server implements it because ietf-ds-ephemeral is listed in YANG Library.   And so it is with all dynamic datastores, but not so for built-in (non-dynamic) datastores (e.g. intended) because there isn't a module to advertise for them (yet).
