Today, Google has published the Google Support Services application to the Play Store, to allow updates without new system updates. Also Google Support Services is only available in some regions, so if you can't load the Play Store listing, you'll know why.
One of the Nexus owner with the Android 7.1 Developer Preview were actually able to receive support as well until Google disabled it. Now the Support tab in settings just has links to Google's online help.
Right now it only works with Pixel devices, but it can be installed on any Lollipop device. This is a bug that will be fixed by Google in no time, but it's interesting nonetheless.
