It will help that side of the process (although, as a sibling has noted, you can CNAME your way into a better-controlled update service), but the challenge of automating cert changes for various non-HTTP services, including various virtual or physical boxes with funky admin interfaces, remains. I don't expect that vendors will do much about that, and it will end up on admins' plates, as usual. There will be much grumbling, but fewer solutions.
