Summary from doc at [1]: "We will on-demand install the Chrome VR dynamic feature module (DFM) on Daydream-ready devices. We will request the install as soon as Chrome updates or starts. If the user starts Chrome from VR (e.g. through Daydream Home) before the VR DFM is installed we close Chrome (on smartphone VR) or launch it in 2D-in-VR (on standalones) and show a toast that Chrome is getting ready."
This replaces the previous conditional install approach (see issue 862719).
