Yes -- power consumption and heat generation. I have an interest in not letting my unused CPU cycles get stolen by (for example) web browser bitcoin miners, because (for a desktop) I have to pay for the electricity used by the computer and also by the air conditioning to cool it and (for a portable) that drains the battery quickly. | |

However, would there be any benefits in preventing a process to use 100% of the CPU when no other process needs it? | |

If you want to limit the amount of CPU usage that a process can take at a time even when the system is otherwise idle, you'll need to set a quota/resource cap. | |
