While I’m very much in the “don’t really care” camp cos I don’t quit Emacs often, I did find optimising my startup time quite educational, and moving to use-package gave me an opportunity to go through every mode in detail, instead of just making the occasional ad-hoc tweak when something annoyed me. I would also point out that early-init exists these days and is the best place for some startup logic (especially bits that prevent UI ever being shown so you don’t get weird flashes of stuff during startup).
