silverpill (npub19yg…wysk) question for you about Mitra. I believe you accept RFC 9421 signatures for GET and POST to inbox and sharedInbox, right? Do you also send RFC 9421 signatures for GET and POST to inbox and sharedInbox, and do you use FEP 844e capability discovery? I'm trying to put together a compatibility table.
