The self-contained thing isn't always true either, for a long time the open firmware inherited from the linux-firmware repo wasn't built from source, we just shipped the binaries. I expect there are other cases in the archive too, Debian doesn't systematically strip generated files from all tarballs and regenerate them. Especially with more AI/ML stuff, where we probably can't even get the training data, let alone afford to train them.
