I was talking about the safe browsing request. Arguably that's even more important to the average user than TLS safety. MITMs are rare, malware sites are plenty. I do think that the favicons could just be integrated. I don't think there's any point minimizing the network in this specific case. "We don't know what data is useful.", sure, but any other data this can be compounded with _already contains the same information_. Though yes, stuff could change in the future. I can't see how it could change in any way to make this useful, but you're right, this isn't something we can predict. That point is valid.
