And how would one tell an idle service that's not doing anything because no one's using it at the moment from a hung service that's not doing anything because it's broken?
You get right back to having to run the service itself to see if it works.
It's really hard to test a given functionality by implementing some other functionality that doesn't exercise the actual thing you're trying to test.
It's a lot easier to test if you car's brakes work by stomping on the brake pedal than it is to design and implement some system to measure acceleration and forces in a bunch of different places and then try to infer if your brakes are working from the data you collect. And if your brakes do keep failing, you put your effort into identifying the failure and fixing them.
