While I agree, and this being the reason I provided it as a file applied
using debian/patches/ and not just a file in debian/, I do not really
care much about upstream.  I do care about appstream from Debian, and
leave upstreaming it in the competent hands of others.  I got 80 more
Debian packages to report patches for. :)

I do not care much which ID is picked.  I made one using the URL in the
Homepage field of debian/control.
