Why exactly it has to be deprecated? We have use cases that require `query-cpus-fast` to exist, but I don't see why the existence of a command that returns extended information is a bad thing. Having a command that synchronizes CPU state is even a requirement if we want to eventually implement "info registers" using QMP. -- Eduardo
