The two aren't mutually contradictory. Quite the contrary.

For EAPI 3, we're aiming to make it illegal to do anything with a flag
unless it's either explicitly listed in IUSE or handled via a number of
special magic profile variables, so you'd either have to list it
everywhere or use one of the profile variables. Once you do that, how
you mask / force it is up to you, unless you need some kind of special
package manager handling for that flag.
