However, IMO it's more basically along the lines of how an operating system/server may recognize case being 2 separate pages and the need for SE's to treat it as such when indexing. There's nothing to prevent someone using the same URL in different case structure for 2 totally different pages. Not that I suggest this but as long as there are operating systems that are case sensitive it needs to be respected.

May be a good explanation. There is also an alternative explanation.
An URL, a subset of an
URI again a subset of an
IRI, opens for trouble when the more advanced XLink model becomes more widespread, unless it is unique.
