So do you mean moving the linking step away from the target frameworks build phase and into an OTHER_LDFLAGS setting in the xcconfig?  If so, you'll lose implicit linking/building, right?  You'll have to add the linker flags to the xcconfig and probably add explicit target dependencies to the target.  If this is what you mean, I suppose a benefit, is that the xcodebuild step that I changed in df7a027 can revert.
