There is some chance for a big mess here, thanks to progress that MS
has already made in this direction.  There is support for ini files
in the Windows api, and MS has at some time said that it might migrate
the ini files into the registry without letting the application using
the Windows API to access the ini parameters know.  So, not even the
program opening the ini files knows for sure.  Reading and writing ini 
files as files already breaks MS's API.  I've not hit a case where it
breaks MS's actual implementation, but it might.  

The possible downsides of all this are stunning, but the upside is that
because the registry is like a database, the programmer using the
registry
does not so much worry about what happens if multiple programs accessing
and updating the same settings might be running simultaneously.
