No, -* is fine, so long as Portage doesn't pass it through literally.
The problem, specifically, is that things like this are totally legal
and are done by some packages:
IUSE="linguas_en linguas_fr"
if use linguas_de ; then
if has linguas_de $LINGUAS ; then
if has linguas_de $USE ; then
So if you were to set LINGUAS="*", there would have to be some magic
way for the package mangler to know that linguas_de exists, even if
there's no mention of it anywhere in any user config files or in IUSE
(and no, the desc files aren't a complete list either).
The reason for this, historically, was that IUSE was used purely for
display purposes by Portage, whilst USE was worked out from everything
in config files, regardless of whether or not the ebuild claimed to use
it. That meant there was absolutely nothing stopping you from making
IUSE incomplete...
