I doubt users immediately think "USE_EXPAND" when they see an underscore.
Portage's seems fairly unambiguous to me. For example:
% emerge -pv1O app-misc/foo
These are the packages that would be merged, in order:
[ebuild N ] app-misc/foo-0::local USE="-modern_kernel"
PYTHON_TARGETS="python3_7" VIDEO_CARDS="radeon" 0 KiB
Total: 1 package (1 new), Size of downloads: 0 KiB
I don't think anyone would mistake "modern_kernel" for a USE_EXPAND
value given the above.
