Either Rust gets an ABI or we need to give up one of the other two principles, which I highly recommend not to do. I think ABI compatibility is achieved by shipping source code only in the -devel packages (similar to what Perl does). The rebuild issue is still there, but it's no different from certain Java packaging practices, and what C++ (with template metaprogramming), Ocaml, Go, and so on currently do.
