However, adding a test to run it with a trivial number of iterations seems reasonable, so I'll add that. I'll also add a meson target for the binary.

Okay, but for what purpose? My understanding during review was that
this was a convenience utility for people who were actively hacking on
the code (and I used it for exactly that purpose a few months back, so
I didn't question that any further). Why does the farm need to spend
any time running it at all?
