I love that about it too. Do you worry that people will try to centralize things like blacklists across clients/relays though? Even with using your own relay, I worry that it will severely impact who sees what you post.

Are you following what nostr:npub108pv4cg5ag52nq082kd5leu9ffrn2gdg6g4xdwatn73y36uzplmq9uyev6 is doing? The clients it supports aren’t natively built for Nostr, and a lot of them are web clients, so you can easily just self host. There’s not much chance of anything ubiquitous happening client-side if you can just view everything from the Mastodon’s app, whose devs have probably never even heard of Nostr.
I think it’s also automating which relays your posts get sent to, so that shouldn’t be a huge issue.
