> No reason the transmission protocol and the application/ui protocol need to be coupled in their level of abstraction
They aren’t as there isn’t any application protocol.
Ncurses is the closest you’ll get.
But several TUI frameworks exist (like ncurses and the charm.sh packages) which abstract the low level let’s call it a wire protocol
Sure, but I’m arguing that replacing the very minimal protocol with a heavier one would not be an innovation nor would it be useful at all as you would always need some kind of low level streaming protocol, unless you’re looking to replace pretty much all of Unix land, but that’s a whole different discussion.
