TODO, from DebConf 2018 WebExt packaging BoF:
- Guide for maintainers to define transitional packages from old xul-ext stuff
- wiki.d.o/RenamingPackages
- see adblock-plus git history for an example
- done in d/control so we can't really automate it in dh_webext but at least
we can give a central documentation for packagers to do it
- better documentation, e.g. syntax for the debian/install-webext file
Other stuff:
- chase up https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=890392
- if chromium maintainer doesn't co-operate, alternative is to add
that file to a webext-common package and depend on it for every webext
