Yes. Although, in this case, I have put the packages I want to install
into my .emacs. So not "silent" at that point. I am doing something

It's easy to add, although I suspect answering "Y" would become part of
the muscule memory.

I forget how package.el works, but it inherits behaviour from that. So,
it will update the package-list (i.e. call home) if your .emacs.d/elpa
is empty. But I don't think it refreshes it to look for updates.

Just so. What this means is someone installing Emacs one year after a
release would (likely) get updated packages, compared to release
date. Whether packages would update themselves after the first start
would be a different question. They wouldn't need to.
