@AutumnMeowMeow@tech.lgbt @antijingoist @fribbledom @zens@merveilles.town that could be an alternative indeed. If you you want to go that route, then one could define an entire extension protocol that allows a terminal to render things in an accessible manner.
But how does da1 work? I don't see it defined in terminfo, so you're suggesting hardcoding an extension to xterm?
