Mobile already does use ESI, but this would be extensions to it.
Not in production. We've done some experimentation with ESI and have some implementations of Varnish ESI in MobileFrontend sitting in a remote branch that by now has suffered serious code drift from master. This is definitely something we'd like to see in production soon, but we are currently having to prioritize other things on our plate higher. We'll make some comments on the RFC :)
