Config being a programming language has insane advantages. Not only can I error check my config in vim or Visual Code, I can do insane things with logic that just don't work in other config file approaches. My laptop is connected to a 32" 4k monitor at work, standalone while traveling, and to a 27" 2k at home. WezTerm "knows" that, and sets things such as font size and line height automagically.
Even more, I can have split logic based on window size, window titles that show me who also checked out a file while I am inside an editor, even per-window color and font schemes.
All apps should use something like Lua for their config.
