Nagging user to install package does not tell to user that GNU ELPA
exists even. Think of new user who installs Emacs to do some SQL
editing and is then asked to install sql-indent. I am using PostgreSQL
maybe 20 years, I do not remember, and I never used that package
neither I need it, and I did not know about it. So in that sense it
did work for me, it promoted package to me.

For new users it is good to think how to offer them GNU ELPA packages,
please put yourself in their mind or look from their view point.

- many users will not know what is this dialogue about. 

- user will not know what is this package about, there is no title or
  description. To really promote GNU ELPA it would be good to tell
  about it. Add the third button "Find more about GNU ELPA" that maybe
  leads to Emacs manual.

- user will not know that package is supposed to come from Internet
  and those without Internet or in local network will be asked and
  then action cannot be performed. Do not assume that many people have
  Internet. GNU/Linux is installed on plethora of computers where
  students, professors, teachers use it without direct Internet.

  Make a check if Internet is available, then ask the user.

- gnu-elpa package could also make one question such as: "May I inform
  you from time to time about Emacs?" -- then if user says YES there,
  it could run automatically and from time to time inform user about
  tips on how to use Emacs or tips how to use GNU ELPA. People could
  contribute to those tips to be shown randomly or semantically in the
  context of what user is doing. Emacs has doctor built-in but not an
  artificial intelligence to guide the user. Why not that way.

- additionally I hope that dialogue works in console too, as I did not
  check it.
