> the new command and commandfor attributes, enhancing and replacing the popovertargetaction and popovertarget attributes. Didn't these just become baseline available? What does it mean, replace them? Will they remove them some day like with import assertions/attributes? Sometimes things like these make me wonder if the people in charge are conscious about that everything they are putting in will stay there forever. You can't just release an update and remove stuff you ("you" as in: the web devs at your company that happen to be in the same company that builds a browser) don't need any more.
