Fair.

All I’m saying is, if someone is trying to impersonate some one and primal requires a nip-05 for their centralized caching server then it would be important to add that to your npub so that the service can “verify” you in some capacity.

It helps with reach in that case; and lookup for npubs. Which is what the OP wants reach and doesn’t want shadowban from centralized cache servers; best to control your own domain and use the nip-05
