I basic used `:defer t` for a while (Doom Emacs lazy loaded under the hood), but when I switched to my own config I decided to just run it in daemon mode and use `:demand t` on everything. I didn't like pauses sometimes when opening a new file while it loaded a package.

Actually, I just checked my init time with that command, and it's ~2.5 seconds. I wouldn't call my config heavyweight, but it does have evil, lsp, vterm, ivy, magic, etc. I am using the native-comp branch though.
