Isn't this whole point of standard? saying what is allowed and what
not? Especially for C++ that tries to separate itself from concrete
implementation and its details.
Goal of C++ is to have same program behavior on a maximum number of
machines and this needs sacrificing some details to make it work
without big overhead.

If tools that give C++ do not match your expectations then switch to
another language that fit your expectations or adjust your
expectations for C++.

Please do not try to push a square peg to a round hole.
