I really would like to be able to pass the -F flag in the target. I have binary libraries (one of them is Firebase from the Carthage build). I can pass them as unsafe flag but then I can't depend on that library as soon as you do that. This is putting me in a bind. I made a proposal earlier but it got no response. This would tide us over until we get the final spec for importing binaries and I would happily update to the final agreed upon way of doing it, once that spec is agreed upon but right now, not sure what to do.
