How would I improve RSS? Three ideas (Interconnected)

Matt has thoughts on RSS:

My sense is that RSS is having a mini resurgence. People are getting wary of the social media platforms and their rapacious appetite for data. We’re getting fatigued from notifications; our inboxes are overflowing. And people are saying that maybe, just maybe, RSS can help. So I’m seeing RSS being discussed more in 2020 than I have done for years. There are signs of life in the ecosystem.
