No no no! That’s really the realisation they’re pushing at, this is fine for routine tests too! In this almost ten year old post the runtime was ~90s, which isn’t too painful. On some threads here, times on modern hardware are quoted as milliseconds or less.

The takeaway might be more: spend time to optimise testing everything, rather than spending time optimising the selection of the subset to test.

Massive caveat of course is that some search spaces are just big, but 32bit space shouldn’t be considered big any more.
