Yes, the thing is, what you are talking about above is a separate problem that cannot be solved at this point. Even more, the solution for that problem would not solve the problem or unnecessary checking for SCCS for systems that have sccs installed by default (i.e. about all commercial unixes and free ones that install cssc). So why not just move SCCS to the end of the list?
