@mint Okay so, I've never looked that close at how authorized fetch behaves, but I have one question, if anybody here is familiar with the behavior....
Originally, the big idea of shared inboxes was that, if you have Server A, Server B, and Server C, and a user on Server A has 1,000 followers on Server B, and 1,000 on Server C, then Server A is delivering to 2,000 people by making two /inbox requests.
My initial understanding of signed fetches is that now Server A is going to do something (the same thing?) to inform these other two servers that there's a status to fetch, and then Server B and Server C are now going to sign 1,000 requests each and make 1,000 HTTP requests that have to hit Server A's backend and cannot be cached, each? @DutchBoomerMan@paula@kirby@PeachySummer
