The meaning of any one USE flag varies widely across packages. I could
never say "I want to enable USE=gstreamer" for every package in the
tree, because I have no idea what it does for most of them. Setting
USE=whatever globally essentially means "make random changes to my
system" -- hence my wording.

The meaning of a USE flag is per-package, so per-package is the only
meaningful way to set them.
