Ready-to-install packages would be awesome, though it would require someone to implement and maintain that package, and there's still configuration complexity for users who need to install that package, and potentially maintain different versions as Swift's ABI converges. Static linking would avoid all that. The ease of deployment of static libraries seems to be one of the killer features that leads people to suffer programming in Go.
