most protocols don't really have official logos. i love our nostrich, but in reality, we don't need to have an official protocol logo. we'll have recognizable brand/client logos though.

I disagree. I think that a recognizable symbol for nostr is super important when sharing socials. If I just write my nostr address somewhere, it just looks like an email. Where as if I have a nostr icon followed by the address, its much more clear that this is for nostr, and the person I'm sharing it with can find me on the client of their choosing.
Even email sort-of has a logo
