Sure, but adding complexity in the form of swiveling charge prongs and a bunch of electronics for a screen just adds more potential points of failure.
There is a market for everything, if it doesn’t sell it will be discontinued. However at this time it seems there is enough of a market and interest in this type of product.
 
The Anker 45W Nano Charger is cute. Size of the old 5w Apple charger (maybe slightly bigger).

I like that it gives the option to "care" charge at a slower rate if I want to. It's fairly interactive for a charger. I've given it a place on my desk with an extension cord because I like it so much lol.
 
What I like most? It tells me the charge of my Apple Device (iPad, iPhone) without me having to check on the device.
