This isn't really disagreeing with me? I can even add to it, for a fun example, knowing where to hyphenate a word can depend on its use in a sentence. (Strictly, I'm probably wording that poorly?) Like, I am largely aware that it is a hard problem. So is just rendering text, at large. The added difficulty for justifying text is still not something I expect to impact the vast majority of sites. If you are willing to break your content into multiple pages, I hazard it isn't a significant chunk of time for most content. Are there edge cases? Absolutely! Most of these are isolated in impact, though. And I do think a focus on whole content optimization is clouding a lot of people's view here. You are not doing yourself any favor by optimizing a full book every time a chapter changes. There is also the idea that you have to find the absolute best answer for justifying text. Why? One that is low enough on a penalty score is just fine. Akin to the difficulty in finding all tilings of a board, versus just finding a single tiling for a board. Or a single solution to the N-Queens question, versus all solutions. If you just want a single solution, you don't need the raw compute necessary to get them all.
