Okay, I'll try it out.

We will have to decide what to do about bundled dependencies. Bundling
the source code of dependencies appears to be standard practice in the
world of Go. The compiler began supporting this directly in the 1.5
series:
https://github.com/golang/go/wiki/PackageManagementTools#go15vendorexperiment

This is the manifest of Syncthing's dependencies, which are bundled in
the same directory:
https://github.com/syncthing/syncthing/blob/master/vendor/manifest

If that manifest is a standard thing, we could make a go-importer that
used it to create new packages.

I don't fully understand Debian's packaging, but it seems that they only
use external packages to provide 2 of 39 dependencies, bootstrap and
font-awesome:
