Given the strength of := binding, I'd discourage against this. Causing portage resolver catastrophes to solve a "it would be nice if ..." problem is a bad trade-off. := Should be restricted to things that it is *necessary* for. What I think is needed is a weaker version of := which is advisory: that is, portage ignores the binding in entirety unless portage options dictate "rebuild things even if strictly not necessary" And this levity should mean portage should be more amenable to break graphs to make install possible. ( Whereas with := , the presence of such a spec causes portage to have tantrums when the underlying dependency changes )
