It's a fair point that specs evolve, and that sometimes includes deprecation. I do feel slightly aggrieved about the `scoped` style attribute being spec'd, implemented, and then dropped shortly thereafter. But overall I feel this approach has worked well over the years. With jQuery for example, I only learned enough to get by working in those codebases, but I committed to internalized all of the standardized DOM methods and Array methods and naive XHR workings. Now in these modern times, jQuery still _works_, but whatever I came to know of it is no longer very useful to me, day to day.
