That's literally the definition of preemptive scheduling.

Yes, but "preemptive" sounds so aggressive. We prefer the term "alternative cooperation".

It could also be cooperative scheduling with a watchdog with task killing abilities (like we have for memory usage, it's effectively cooperative + OOM)

No idea why you are downvoted for quoting the literal textbook definition.
