By accident. It's a bug in use-package.
(use-package foo-pkg :commands <commands-to-autoload>)
Creates autoloads for all the commands in <commands-to-autoload>, which
can be a symbol, or a list of symbols. But nil is also a symbol, so
passing an empty list makes an autoload for nil (because use-package
checks for symbolp before listp), rather than making autoloads for 0
commands.
