Earlier quoted context omitted.
How often do you restart it though? Mine lives for days or even weeks sometimes, and is only restarted when it gets updated. When saying "fast" I definitely meant it as "all the operations it does while alive" and not "how many times per minute I can restart it" (lol).
When I need a terminal, mod+enter spawn one and close it. I'll often do this to download a file, start yt-dlp, mpv etc. The session is all tmux so I never keep the window around when not in use.
Still doesn't invalidate its usefulness, too. Alacritty in particular is often times a better Unicode-rendering citizen compared to other terminals.
