[plt-scheme] Addition of #:exists keyword to copy-file et. al.?

I find the #:exists keyword hard to remember, but I think it would be  
easier to recall if it were used more widely.  Is there any chance  
that, say, "copy-file" might be augmented (er, so to speak) to accept  
the #:exists keyword, or would this make for poor cross-platform file  
system cleanliness? This would also address the irritating need to  
check for a file's existence before copying it in the case that  
overwriting is desired. It appears that 'rename-file-or-directory'  
and 'make-file-or-directory-link' might also productively use this  
keyword argument.
