Why??? :-)

You mix up a NECESSITY and SUFFICIENCY.  In order to make checks for
failures it is NECESSARY to check a return value, but nobody says it
is SUFFICIENT. But if CHECKS FOR FAILURE IS NECESSARY,
warn-unused-result does its job, it implements minimal checks and
produces appropriate warnings/errors. Of course, warn-unused-result
cannot replace human :-)
