It's not a crazy idea. Go actually works that way already; the runtime of Go is implemented in Go. For example, here's the sweeping component of the gc: https://github.com/golang/go/blob/master/src/runtime/mgcswee... But that doesn't mean you can get a Go without a runtime; the final executable's GC may have come from compiled Go rather than something else, but it still irreducibly has GC in it. The whole thing is bootstrapped, so at any given time when some bit of Go code is running, it is supported by GC and the rest of the non-optional runtime, even when compiling code that itself is going to be the runtime of some other executable in the future.
