Yeah. IMPLICIT_IUSE needs the whole redefinition of IUSE_EFFECTIVE etc to make sense. Historically IUSE was purely for visual effect. That went out of the window when we got USE dependencies, but for various reasons the opportunity to make IUSE correct enough for USE dependencies to work was missed. Right now use dependency defaults are moderately broken, since their wording depended upon a feature that got dropped. We can't start injecting things into IUSE until we have a consistent definition of IUSE_EFFECTIVE. -- Ciaran McCreesh
