This is still an issue today. The thing is that IDL supports more arguments than that. How many exactly I don't know, but more for sure. That's a compatibility issue.
On the same topic, the /ALL, /VARIABLES, /ROUTINES, ... keywords are not supported, and no error message is displayed to inform the user of that fact. There is actually a message for /ALL, but it never displays since the procedure returns "% SAVE: no VAR. provided, nothing to do" first.
