No, he was definately talking "in theory" about an idealized switch
that, when active, would make the entire operating system do *exactly*
the things described in (whichever chosen) standards and *only* the
things that were described in those standards.  No violations, but also
no extended behaviour either.  His claim was that this is one thing
that, if an OS had it, would instantly make it wildly successful.  (Not
that I necessarily agree, but I still think it's a good idea.)

It wouldn't be for end users - it'd default to off and they'd never even
have to know about it.  It'd be for developers who want to make sure
their software *strictly* conforms to standards.

I only wish I could remember who it was, because Google is definately
not clever enough to let me find it again without knowing his name...
