That's indeed probably true.

That's a non sequitur:
a) even though the original code was written a long time ago, it has  
been changed many times since then
b) if it isn't broken, don't fix it. Example: changing all occurrences  
of "string" into "shortstring" will break the system unit. The reason  
is that a "var a: string" is an "openstring" parameter (with a hidden  
"high" parameter that tells you the size of the variable that was  
passed in), while "var a: shortstring" is not. So at the very least,  
you'd have to change var/out parameters into openstring rather than  
into shortstring.

Adding support for new functionality (such as unicode file names)  
would obviously require revising all of that code, but that's because  
the context changes rather than because it's old.
