Ferrocene has donated their specification to the project, so there absolutely is a specification now. What you can argue is that the memory model isn‘t fully defined, but it‘s almost certainly going to land somewhere around stacked borrows or tree borrows. Arguably C doesn‘t fare much better in that regard though as it doesn‘t even properly define its pointer provenance model either and Rust is much closer to defining its.
