Too bad QEMU doesn't support it. So it's still a long way.

Balloon should be able to cover most of the use cases. You have overcommit and can reserve only a part of RAM, then change the reserved amount which adds more RAM resources.
OS still sees the same (maximum) size, but effectively it allows similar usage as hot add ram
