Sure, but the nuance here is there is a (otherwise usable) range of values for which the timers are only ever "after" instead of "at or after". I.e. the lower bound is artificially increased while the upper bound remains unlimited.
I don’t think “artificially increased” is correct. See your sibling. If the runtime waits until expiry, and only then adds the task to the end of the work queue, there’s no point at which any delayed work could happen at expiry except the work to place it on the end of (an empty) queue.
Any busy runtime (e.g. one with lots of parallel tasks, plus anything running less than optimally) will have a delay.
