Debian has been like this in practice for at least 25 years (when I first switched to it).

The builds weren’t reproducible back then, but never mattered in practice for me personally. Now, the vast majority of the packages have reproducible builds, which is good enough for me. (Though these days I’m using devuan because I’ve never seen a stable systemd desktop/laptop that uses .debs)

Debian isn't source transparent in the same way tho. (I'm mostly nitpicking). That said, the contributions that Debian has made in terms of reproducible builds can't be understated. They built a wonderful foundation for the likes of nix and guix to build on.
