Even without these concerns, there's the fact that `emacs --batch`
implies `-q` and that undoing/overriding this `-q` is not trivial if we
want to do it faithfully.  I think it might require changes to
`startup.el` to better expose the code that selects and loads the init
file(s).

As for the risk of those init files burping, maybe we can "live with it"
and claim it to be a pilot error: either the users fix their init files
or they can't use `package-quickstart`.  Luckily for us, daemon mode has
made it a bit less common for init files to fail in batch mode, because
if they do, they will also fail in daemon mode.
