I totally agree with doas being a good program with really good rationale. I also get that suckless does have a bit of a reputation that isnt for everyone (I've heard that it's basically impossible to make a PR to any of their projects). Theyre obviously not philosophically identical, but I mentioned OpenBSD because its an excellent project that deserves more mention and a lot of the criticisms for modern software design in this post and thread are addressed by their design philosophy. That said, the compiling issue aside I think the overall embrace of simple, self-contained, C code is shared enough where you could compare the two.
