ATC radio for cabin on airlines besides United?

I live in Atlanta and thus normally fly Delta. Once a year I fly out
West and need to do a short SFO-LAS hop and use United for it. Each
time I've been delighted with listening to ATC for the whole hour, as
provided by United on one of the cabin audio channels.

Does anyone know if any of the other airlines will ever realize how
awesome this is and offer it too? Gawd, I'd pay extra for that ...

I dont' believe any other airlines think anyone cares. And, in truth,
there probably aren't a lot of pax that do care. I'll be flying out to
Atlanta on Monday from California on Delta so I guess I'll have to work
on the trip, can't listen to ATC.
