Eh, I'm just picking my battles here. A Release Notes launcher that
starts Firefox is not good and we should get rid of it, but it's not
very bad either and if the release notes people want another cycle to
rethink how to present the release notes, well why not let them have it?
Another thing we could do is add it as a default web app. GNOME Software
requires "epiphany-runtime" which is all of Epiphany except the desktop
file, so that it can install and remove web apps. Well, why not make the
release notes a web app -- then the release notes team gets to keep the
desktop launcher, and we are happy since it's a real application.
