The argument about parsing twice doesn't seem very good to me. Vim and emacs are also parsing keystrokes, should we abandon them too?

The cynic in me thinks it's more likely that because kitty offers tmux features he wants to lock users in to his product.

Not that KiTTY, this kitty: https://sw.kovidgoyal.net/kitty/

But it's also foss, so, you're still right.
