  And didn't stop doing this until 2020! (Specifically Emacs 27.1, which replaced "unexec", which dumped the process image, with the "portable dumper", which despite the name does not.)

    And you could still use the unexec method until this very latest release a few days ago, if you didn't want the pdumper.
