The point of wayland, though, is that back then 13-year-old you would get an application that "works" but to support myriad things (like HiDPI) you'd have to DIY it. Whereas now, sure a 13 year old perhaps won't write directly to wayland's APIs, but you'll use a library and have a much more globally usable result. And honestly probably have a better time - less effort for the same result, and with a more maintainable project in the long run.
