Re: on the customer side I don't know, I still see a "base" phone, or several, being around for some time.
Doesn't mean it won't have further features, or use different frequencies ("LTE"). Perhaps not quite as 'dumb' as they are now, but then again, even the most basic phones these days continue to gain more features (camera, color screens, voice recognition...).
Your analogy also misses the "size factor" - smaller TVs, with fewer features still exist
