This is exactly the reason why we allow host system to see all the
containers/VPSs/processes.

Otherwise monitoring tools should be fixed for it, which doesn't look
good and top/ps/kill are not the only tools in the world.
Without such functionality you can't understand whether you machine is
underloaded or overloaded.
