I'm actually surprised there is no specification. It's how I thought languages were written: spec first, implementation later. Do RFCs serve this purpose?

That requires a complete picture and all possible use cases from the start. Initially when a language is new and hardly used there are much to benefit from flexibility and trying new concepts. Then as the language matures, a more formal process is needed to ensure stability. There is a reason these discussions comes now, since rust is in a very stable phase.
