@evan not necessarily disagreeing, but short lived certs (they have 6 day ones now!) basically render most of the hassle of cert revocation pointless - by the time you discover something happened and that you should revoke the cert, it has only short period of validity left, so either you don't have to bother with it at all, or you need to keep it on the list only for short time.
Also, yeah, forcing automation, which makes rotation pretty painless, as opposed to the big yearly event.
