Looking at Amethyst, I like community notes appearing in the main feed as it shows the community name which can help attract non members to join and participate.

In general, i anticipate clients gradually adding improved filter support. Amethyst's "All Follows" feed will eventually get as noisy as Global, but from that users personalizations.

As long as we work to give users the tools and a meaningful UX around it, I dont see the harm. Much better than imposing view restrictions that may force way to many hops to drill down.
