Folks who prefer "-c" even their platforms all are capable of "-u"
may miss this, but I think that is a very small minority, and they
would be OK (it is after all only needed when diagnosing test
failures of our test suite, and by definition, those who are working
to improve Git would know how to read "-u" output).

I am not sure why you need to drop this one?  This is more about
switching between "diff" and "cmp", and there are reasons why folks
prefer latter especially when they are not debugging the tests.
