please let's refrain from getting into that back hole.
Different people measure different things that they perceive important
for them. I doubt that the "optimization to int main() { return 0; }"
would be useful to everybody.

that may be a decisive criteria under given circumstances; it takes
more justification to qualify it as "stupid benchmark". We can either
acknowledge "oops, we fumbled that case; but we are not going to fix
it" or "well, we should not have done that; it should be fixed".
But handwaving with "stupid" qualification is not helpful.
