Users are not beta testers. Forcing inconvenience on users to benefit
developers is not justified for a relatively minor issue like this.
Changing the default here would have a huge impact, I think probably
some developers do not realize the impact that changing messages or
output has on people developing large systems for which they expect
stable compiler output, e.g. for test cases.
