No, this is perverse in the worst way possible. It's incompatible with modern debuggers. It's incompatible with shared libraries. It's limited to a feature-poor "unified" API (that might as well be seen as a crippled VM). It's complex in both interface and implementation. The bad aspects of Unix made even worse. The justifications make no sense whatsoever. It wants to do future-proofing but invents an adhoc "VM" with hardcoded OS interfaces that are meant to be treated as private. For macOS, I doubt binaries will work in the next release or two, nevermind 10 years. It's a fun toy or troll, but if you're looking at this for serious work I suggest you steer well clear.
