Terminal emulators are pretty niche. I also tend to stick with what's included with the DE.
I've only used a third party terminal when I used gnome. Blackbox, as the one included in gnome at the time was still using gtk3.
Imagine being this guy above me and thinking that the percent of people that would switch out from their default shipped DE terminal emulator is anything but a minority 🤪
Nah, the world uses what's there. It's a small subset that even works on them directly. See also: xkcd meme about infra being supported by one guy in some random state.
