I think you probably misquoted this part of my reply with the other one I talked about sub-domains. This quote I was talking about domain extensions (TLDs) not sub-domains. Something like pinterest having multiple pintrest.*** not sub-domains ***.pinterest.com that I know kagi will currently would do.
Also I think that is not a healthy default, at least there maybe some cases when you want to block(pin/raise/lower) specific sub-domain/s but not ther others. For example I might want to raise gist.github.com but not github.com or any other *.github.com.
