So now everyone on the planet has to suffer from slow response to esc keys because xterm is too lazy to fix it properly. And its not a "few milliseconds". Terminal bytes can come over networks with arbitrary delays, so you either get inaccurate key presses causing potential data corruption/loss or insufferably long delays. It is this kind of lazy thinking that has bedeviled this poor ecosystem. Yes programs need to know about an extended set of key combinations, because lots of programs just spill escape codes they dont understand to the screen. So you cannot produce such codes arbitrarily, only when a program indicates it wants them. And as is usual with xterm, it didnt bother to think this through. It has a facility for requesting these extended keys, but that facility may or may not work. And there is no way to detect if it has short of waiting for those keys. So if a program wants to say, present a different interface in terminals that support extended keys, it cant do so, because it has no way to know if the terminal does support it. I dont need a keyboard that supports physical keys. I can repurpose unused physical keys as modifiers. Its nice you dont care about num lock and caps lock. Its not so nice that you are foisting your lack of care on the rest of us. Let me paraphrase what you said about keyboard layouts. "Something was not done previously and therefore it should never be done". Support for layouts means pressing ctrl+letter can work even on a cyrillic keyboard, but of course, terminals have never done that, and everyone speaks english anyway. So no one cares. You suppose its useful for games? Try making a game that uses keys for real time control without release events. Autorepeat my ass. But ofcourse, no one cares. Are you in the habit of assuming that because you dont care about something, everyone else also must not care about it. xterm absolutely shouldn't. it would make a pigs breakfast of it. I am very happy it didn't. What you should do is stop advocating for a broken, half assed hack.
