"Make" (etc) are not really my concern, but the behaviour of TeXworks
is.  If TeXworks can decide whether or not to conceal the log file based
solely on the status code returned by TeX (XeTeX, etc), then that status
code should (again, IMVHO) be able to indicate "things were not right"
as well as "things were so badly wrong that I had to interrupt the
compilation in order to seek advice from the user".
