Magic files are one thing (and just personally having a filenane beginning with + is just damned ugly). You also even have magic folders, which for me was a first.

Even if I could ignore that, for my super tiny hobby project that I tried Kit with, the routing ended up being strewn across a million folders and files that are called +page nested in (page) folders, and a super tiny app turned into a nightmare to navigate and find things in. I didn't even use any of the stupid SSR stuff, just SPA mode, I can't even imagine what it ends up looking like with +layout and all the server-side files
