I'm quite saddened the web has had to rescind so many features (high-res timers, shared memory, memory profiling). It's worth noting that most of these high-end capabilities had just gotten outright disabled for a time, when Spectre/Meltdown hit. That they got turned on at all is a notable improvement. https://web.dev/why-coop-coep/ https://web.dev/why-coop-coep/ I don't like some of the candor of the article. Treating cross-origin activity as a mis-feature is a great mis-service to the web: it's not really much of a web, imo, if sites are restricted to talking to themselves. That the web standards crew is happy to shit on this range of capabilities, to write new standards that walk the web back: it's a harsh regression, by afraid leaders. There is a lot a lot a lot of trouble here, in these domains, but this desire to just cancel the feature & walk away, to make the web one where sites have to work & play only with themselves: it's a death knell, against the spirit of the thing, deeply. That it's so inconvenient & troublesome to standards authors, so difficult for browser engineers, that it (used to be) a hazard for sitemasters: I'm sorry for your suffering but good things & great powers have a price. You're wrong to want to shut this possibility out. Easier path that it may be.
