The “just” there is doing a lot of work considering the devs themselves disagreed. Sorry, but, I’m going to trust their judgement.

…also the whole networked displays themselves was what caused a lot of problems, according to the devs. Using it for a modern display stack was like trying to fit a round peg in a square hole. Terminals have fallen out of favor ages ago, and personal computing devices today favour things like high responsiveness, clean images, and high refresh rates instead. And we got enough computing power to just stream a video stream directly if that’s needed now.
