Blocklists supported by the browser would be a good idea, but what makes Firefox with uBlock Origin more powerful than Safari with a blocklist (and no uBlock Origin anymore) is that you can’t remove annoyances easily or block certain elements quickly. One could argue that this feature is not used by many average users, but Firefox hasn’t been the browser of the average user for a long time. So it’s all the more important that it doesn’t ignore its evangelists and power users. There is a place for browser native blocklists. There is still a worthy and much needed place for uBlock Origin in that world. An API where an extension could tell the browser to remember what elements to block (not just URLs) could help. But this is probably better implemented by absorbing, into the browser, (some or most of) the work that uBlock Origin has done.
