Putting aside the signed binaries, which clearly cannot be reproduced
bit-perfect, it's really not that much smaller - versions don't matter
that much as we use the same env for each major version, and most
packages are dependent on the server build, which requires the
majority of dependencies. The only real time saver would be to only
try to reproduce a subset of the supported platforms.
