The purpose is not to advertise the archive itself, but the features
provided by the packages it hosts.

Yes, it's quite dry and deserves a fair bit of work to make it more
user-friendly.

Yes and no: Emacs shouldn't initiate a network connection without an
explicit request from the user, so we have to ask first.

But you're quite right that the question should be more explicit about
where the package will be fetched.

I'd welcome help with all this UI-side of the package.
