Unfortunately, I don't think they plan on bringing this back. They have been migrating parts of their API over to minecraftservices.com without any apparent warning, and there seems to be no documentation for the new API. Kind of annoying that they decided to break the original API as well. I've tried contacting their support in regards to this issue and the changes coming with the new API, both were met with links to the FAQ. Hopefully, Mojang comes out with something as they further deprecate the old API.
