I've found what makes me build not directly in the root directory: the
manpage for dh_install suggest building [large] packages in debian/tmp.
Also, dh_install will fall back to looking in debian/tmp for files, if
it doesn't find them in the current directory.

I agree, it's not a strong policy, but I still think it makes sense.

You are correct, the policy could do with some improvement.

The general idea is that you would have a get-orig-source target in
d/rules that downloads the tarball, makes is compliant with DFSG, and
recreate a new tarball. That is the tarball that will be used to rebuild
the packages in the archive, or that will be downloaded by `apt-get
source`. See the previously mentioned example from Marcelo.
This is not specific to your package, and in fact not general to
javascript packages, but general DFSG process.

Cheers,
