I don't know how big the strongly connected component has to become so that you might call bootstrapping Debian "nearly impossible" but last year there were just two new Debian ports: arm64 and ppc64el. So apparently it is still within human reach to build Debian as a whole from scratch. I think what the graph shows is just that it's getting harder and that we need automateable tools to do the whole thing for us. This is what the new "build profile" syntax is for that was introduced with Jessie.
