I thought we decided we didn't want to pursue that idea, based on Joshua's objections, and instead we wanted to figure out a way to compile universal with the 10.14 SDK, maybe by making a universal 10.14 SDK, or maybe by forcing the build to use libsystem.dylib instead of the tbd file as suggested by Jack.
