Why would anyone ever be forced to upgrade their server?

No-one is suggesting that browsers _only_ support short-lived certs!

The reason for dropping it is to save the N hundred milliseconds
(sometimes much more, if network is bad or server is down) that you have
to wait before you can actually go on and request data and display it to
the user. This is the big advantage of no-AIA. It's not the miniscule
cert size saving.

Great :-)

Nothing, but they are no advantage to anyone unless you can also omit
the revocation pointers. Which is currently not permitted, hence this
discussion.
