Yes, but configuration parsing happens way earlier than the actual
use of the option (which is decided after configuration and then
command line is read), so the users would probably have hit the
error message and corrected their configuration before they can even
see this error message, no?

I guess I am repeating myself, so there may be some case where a
stale variable can still be in the user's configuration file and the
user can hit this error message without seeing the other error
message about the stale configuration variable that I am not seeing?
