I am fine with that because it's essentially what we did
previously. It's just less convenient to have a patch instead of a
separate file.
However, most Emacs packages (outside of Debian I mean) don't
automatically register the mode. The documentation just contains the
appropriate snippets to do it. So, it's unlikely, I think, that this
will be merged upstream.

I did notice that after some testing.
I have tried to convert js2-mode to dh_elpa but got this error when
installing (even when not upgrading):

Maybe the helper is confused by the "~" in the version number?
