"Add to Home Screen" is, to me, another QR code. It's "easy to use" and "available on every phone," but average users have no clue about it. I'm sure you can do it on Android, but I have not the slightest idea how (and I've been using Android for 7 years).

"Instant" apps are likely going to take over the space that this feature was supposed to inhabit.

Would love to hear more too. We are currently experimenting with add-to-home screen vs installs.

P.S there is really nice library for it http://cubiq.org/add-to-home-screen
