If I wanted to add the [foot terminal](https://codeberg.org/dnkl/foot) (TERM value `foot`) to this list, how should I go about it? Open a new PR?


foot is one of the first terminals to support (and was made explicitly for) Wayland. Many people still foot daily, and prefer foot over Alacritty or Kitty due to it being simple and lightweight, while still having a ton of features.
