I find the inclusion of every federated instance in ‘All’ fairly annoying. New tiny/niche/vanity instances get added by default when federated. There ends up being too much duplication and stuff I’m not interested in.

I’d much rather a system that only includes the local instance by default with a way to discover and add other instances.

My instance block list is long but there’s always new instances to block. For me, this a design flaw of the fediverse.
