Indeed.

But, by choosing a design that has that sort of isolation wired into
it, you end up ensuring that they cannot be used for anything else,
rather than creating a general-purpose mechanism which can, among other
things, be used for virtualization.

As the Jaron File notes (see the entry for `uninteresting'), there is a
strong tendency towards general-purpose tools which solve the original
problem as a special case.  I'd much prefer to see this done that way
(though, admittedly, that constitutes armchair quarterbacking).
