The point I'm making is that one cannot forsee what the user will do
(run) at build time. Thus sticking with a big fan warning is a
sensible thing to do. If no-one pays attention to the warnings (I've
been guilty a few times as well) then it's their own fault - it's not
like we print (m)any and things get lost amidst the noise ?
