I think we need more. The button to copy the feed URL alone will leave users bewildered on what to do with the link. While I don't see a chance to integrate RSS reader functionality back into the browser given the current zeitgeist of minimal UIs for them (outside of Opera/Vivaldi), to lead users from feeds to feed readers is reasonable. I'm not saying feasible for us, but reasonable as an idea ;) But sure, the button to copy the feed on by default would already be a great improvement.
