I would print something on stderr. POSIX is ignored often enough and a
ton of scripts are using the cancerous GNU extensions and other
extensions. If we just "ignore" them, there is no learning effect or
push for change for script writers, so maybe we could add a warning
while we ignore them, so when you run a script that makes use of these
mostly useless flags (which we could also tell them), then this might a
push in a good direction. What do you think?

With best regards
