I hate this too, but I would distinguish between the terminal and the shell. For most of us on Linux or OSX, they might as well be one and the same, but formally speaking, they are still separate. There are many places where VT terms are deployed -- especially in embedded -- where there is no shell, and thus no security issue.
This is barbarianism. This is Babel. Too many dunces trying to turn VT220 into Google Chrome. The long-term effect: the ruination of terminals. You can already see it. Try to run newer terminal apps on classic hardware terminals. Most of the time, you just get garbage, since nobody seems to bother to even check termcap anymore. They just directly shit out whatever bleeding-edge escapes that vte/iterm2/ghostty or other barbarianisms support as of the last five minutes.
If you want something half-way between VT220 and Google Chrome, please be original and make something new, rather than wiping your butt on a standard that is still somewhat functioning.
The prostitutes pushing for this do not deserve words. They deserve ridicule, public humiliation, and worse. The computer is a tool. Whoever would encumber it is an obvious shill for the corporations (google/apple/microsoft) who would like to attach an identity (i.e. tolls and controls) to actions prior generations could do freely and without surcharge. It is a modern-day enclosure movement. Its proponents should be juicily spat upon.
