In my profile as in /etc/portage/package.use/  , yes. Specifically I
tested VIDEO_CARDS: *

I *didn't* try to mess with my in-repo profile though.  Given that
repositories may well need to follow PMS, and the USE_EXPAND: * syntax
is a portage'ism, this is why they are being rejected in the
transmode-overlay case.  I certainly can't find an example of this
syntax in the gentoo repo.
