I know no OS that itself relies on the extension, except in a CI/shell
that can be overridden or at least adjusted to some extent. But there
certainly have been many before and other than MS that supported an
extension or equivalent field that most or all vendor-supplied utility
software _did_ rely on: at least RT-11, RSX-11, TOPS-10 and -20 -- and
(nonvendor) ITS to some extent, VMS, I think AOS/VS, and VM/CMS. And
CP/M, which is no child of MSDOS although a case can be made for the
inverse. Even in Unix _some_ utility software relies on extensions.
