alt Hacker News> It would be very easy to just ask them. Instead we still insist on shipping a fixed terminfo or termcaps DB.
Isn’t the terminal info easily modifyable? You can add new entries at both the system and user level.
The only actual issues are capabilities. But just like all protocols, there’s need to be an agreement between the software and the terminal. And gradual degradation if some capability is not there. I have more issue with some software hardcoding escape sequences than with not being able to add new terminal entries.
Yes you can add entries, but it's still an awful design. It's like if the web didn't have media queries and such and instead everyone ships a big database of user agent strings that websites check in order to know what features they can use.
And no, caniuse or browserlist are not that. Yes they contain data on what browsers support what, but that's only to guide your compatibility decisions. You can still opportunistically try to use a feature and a new browser that's not in the DB can handle it correctly without having to lie in its UA string.
