I think I have an idea where you're comming from, but that's still a little too harsh. In case of programs written in go, it's not really all that complicated I think: go pretty much "solves" (ignores by forcing vendoring in) source/build dependencies -- and the resulting build is only a binary and resources. So it's a pretty good fit for stuffing in a cpio/deb-file -- I think what's mostly lacking on the Debian side is motivation (some package or other that is written in go).
Actually, come to think of it... might be time to have a look at apt-get source docker.io...
