sap.ui.model.odata.v2.ODataModel support for Odata V4

I use multiple Odata sources, and during testing sap.ui.model.odata.v2.ODataModel I was getting some MetadataFailed exceptions. I do not get these exceptions with sap.ui.model.odata.ODataModel

I tracked this down to any V4 model, such as http://services.odata.org/V4/Northwind/Northwind.svc/

I am using openui5-sdk-1.32.11, but get the same issue with openui5-sdk-1.34.3

Not a show stopper for me, but I wonder if anyone has some insight into this issue.
