You assume the circuit design engineer always knows what he does an
what he has to specify. Especially which freedoms or constraints for
bare board mfg and assembly.

I am engineer and PWB layout is my main business. Often I have to
tell the customer which stackup he needs or whether it doesn't
matter. Often it is totally up to me to make a ugly wired chaos
prototype which ran more or less well on the engineer's desk to an
EMI compliant, manufacturable product.
