Since it is a public API, it will be supported for all Dojo 1.x
releases. You are safe to continue using it.

When you do a raw post, you are deciding to handle encoding of the
request body yourself. Since Dojo cannot guess what kind of encoding
you will do, then you need to specifically tell it. Also, it is not
uncommon with other dojo.rawXhrPost calls to want to set other HTTP
headers. The headers object seems like a nice way to allow you to
specify all the headers you want.

If you have:
handle: function (data, args) {}

then args.xhr will be the XMLHttpRequest object. You can do a test for
args.xhr.status to get the HTTP status code and branch your code
accordingly.
