Just because something is machine-facing, doesn't mean it isn't also user-facing, as users' write the machines that talk to QEMU. deprecated.rst documents *everything* that changes in one of our publically consumable interfaces, whether CLI args, QAPI schema, HMP commands, or device impls or more. There's a whole section there just for QMP command changes already.
