Like every benchmark, it has its uses. Just last week I was tinkering
with several high level languages in order to see which one would
start, do a fairly trivial task, and shut down, in the shortest space
of time. Why? Because I wanted that trivial task to be added to our
rapid-deployment sequence at a point where a human would be waiting on
it, and the task itself wasn't critical (it was an early-catcher for a
particular type of bug). Delaying my fellow developers by even one
second at that point would be unacceptable; the various options at my
disposal took anywhere from 250 to 750 ms (cold cache, which is what
matters) to run. Yes, I know a second isn't long. But I was trying to
sell a concept, and if I can say that it adds "practically no time" to
an interactive action, that's a lot better than even one second.
Considering that rapiding took about 1200ms (ish - again, cold cache)
previously, adding even just 250ms is noticeable. Benchmarking an
empty program would get very close to this actual real-world scenario.

(Eventually I merged the functionality into an unrelated script just
for the sake of saving on interpreter startup time.)
