"Reproducible builds of Debian as a whole are still not a reality, though individual reproducible builds of packages are possible. So while we are making very good progress, it is a stretch to say that Debian is reproducible."
In my experience, if you have a single home made package in C it is pretty easy to make it reproducible
It's funny that to prove your argument you're quoting a paragraph that says exactly otherwise. Not to mention, NetBSD builds are about the OS, that's kernel, tooling, base and so on, and not about packages, as in Debian's case.
