If you are annoyed by people who boost too much (like me 😁 ), you need not mute them! Just go to their profile and choose behind the 3 dots "hide boosts from @xy". This is also the easiest way to get only original posts by a followee.
Rather than having to fiddle with settings per-person, I'd love to have a separate links / URLS for "things directly posted by everyone you follow" and "things boosted by everyone you follow".
