Does ODataLib for OData V4 support Atom payload in requests?

I am trying to use ODataLib for OData protocol V4 (Microsoft.OData.Core) to generate payload in Atom format. I ensured that Content-Type and Accept headers refer application/atom+xml, however a call to CreateODataEntryWriter always result in exception:

Microsoft.OData.Core.ODataContentTypeException : A supported MIME type could not be found that matches the acceptable MIME types for the request. The supported type(s) 'application/json;odata.metadata=minimal;odata.streaming=true;IEEE754Compatible=false, application/json;odata.metadata=minimal;odata.streaming=true;IEEE754Compatible=true, application/json;odata.metadata=minimal;odata.streaming=true, application/json;odata.metadata=minimal;odata.streaming=false;IEEE754Compatible=false, application/json;odata.metadata=minimal;odata.streaming=false;IEEE754Compatible=true, application/json;odata.metadata=minimal;odata.streaming=false, application/json;odata.metadata=minimal;IEEE754Compatible=false, application/json;odata.metadata=minimal;IEEE754Compatible=true, application/json;odata.metadata=minimal, application/json;odata.metadata=full;odata.streaming=true;IEEE754Compatible=false, application/json;odata.metadata=full;odata.streaming=true;IEEE754Compatible=true, application/json;odata.metadata=full;odata.streaming=true, application/json;odata.metadata=full;odata.streaming=false;IEEE754Compatible=false, application/json;odata.metadata=full;odata.streaming=false;IEEE754Compatib...' do not match any of the acceptable MIME types 'application/atom+xml'.

Here's the sample code that cause the exception:

    var writerSettings = new ODataMessageWriterSettings();
    writerSettings.SetContentType(ODataFormat.Atom);
    var messageWriter = new ODataMessageWriter(request, writerSettings, model);
    var entryWriter = messageWriter.CreateODataEntryWriter();

I inspected the library code and found that ODataMessageWriterSettings has a property EnableAtom but this property is declared as internal, and it doesn't seem to be set from inside the library, so it looks like it is always false. I know that Atom format is obsolete in OData V4, is it supported for entry payload generation?

ATOM is disabled since DataLib 6.3.0 release, see release note. Actually, you could use an ODataLib pre-6.3 release to generate ATOM payload, but new features in V4 may not be well supported.
