I see what you mean. Yes, one of the advantages of the Jumble model is that it allows for that kind of customization, and if it's clear to the user that they're browsing a relay and not the abstract concept of their following feed then I see it as pretty much ok.
I was thinking that you wanted to get rid of the following feed and proposing that Nostr clients switched entirely to this other model (rather than just adding a feature for browsing relays).
