Cloud providers have live migration now but I guess they don't want to guarantee anything.

It's better (and better still with other providers) but I naively thought that "add more RAM" or "add more disk" was something they would be able to do with a reboot at most.

Nope, some require a full backup and restore.

Resizing VMs doesn't really fit the "cattle" thinking of public cloud, although IMO that was kind of a premature optimization. This would be a perfect use case for live migration.
