Throughout the years, I always stuck with my own method of organising my config files with my own style which is all based on eval-after-load. Never felt any motivation to move my things to use-package as I am quite happy with what I have. Well, I feel like I should give it a fair shot now that it comes out of the box.

Just upgraded on my laptop. Config didn't break, so that's something. I look forward to investigating the new features, sounds like I can probably refactor my init.el a bit now that treesitter and use-package are in the base.
