- [scroll-customization-api] is there still interest/ongoing discussions for scroll customization? · Issue #1118 · w3c/css-houdini-drafts
  - https://github.com/w3c/css-houdini-drafts/issues/1118#issuecomment-1854163406
  - Rick Byers が Extensible Web Manifest について言及
  - I still agree with what I said about higher-level APIs being fundamentally limited and low-level primitives being more powerful. But I also now think it was a grave error for me to argue against prioritizing such APIs like snap points in favour of getting scroll customization primitives (I just underestimated the challenge by at least an order of magnitude). While I still agree with much of the philosophy of the extensible web manifesto, I think we got the priority wrong then. IMHO in a world of quite limited resources for browser engine investment (especially considering across WebKit/Gecko/Chromium) the first priority should be to ensure the 95% use cases can be done easily and (crucially) in a highly-performant way with declarative APIs. Making the remaining 5% possible in some way is also important probably less so.
  - 低レイヤーの API の重要性は認めるも、実装としては 95% のユースケースを満たせる宣言的な API を優先した方が良い
