Do they really? As far as I can see, we have a bijection between supported nix systems and chez-machines, with the behaviour when looking up unsupported systems being undefined. This means that nix- system->chez-machine is well-formed in contexts outside of supported- system, e.g. also for the 6/9 patch. Cheers
