The client currently only accepts '3.0' which directly conflicts with other clients (like OSC). It is not currently possible to export OS_IDENTITY_API_VERSION and have it work properly for both clients. In addition, the way it is written now "DEFAULT" is not really a proper default, as 2.0 is the fallback. This change resolves that inconsistency.
