In addition to the simplified CLI and the license, there is also the mention of using Unveil/Pledge throughout the code. That seems consistent with OpenBSD and probably is a big part of this. AFAIK, that is also something that would make the code fairly tied to OpenBSD at the moment at least. I've worked with stsp for a number of years on SVN. He is a thoughtful developer. I am not sure what got him started on this but I hope this comes together for him.
