There are several packages that weren’t included in Built-in Atom packages in slightly earlier versions but were added later.

So it’s good to periodically maintain by removing default packages from your apm stars favorites management.

By the way, when you apm install packages that are included in Built-in Atom packages, warning messages started appearing.

apm install archive-view

The archive-view package is bundled with Atom and should not be explicitly installed.
You can run `apm uninstall archive-view` to uninstall it and then the version bundled
with Atom will be used.

Installing archive-view to /Users/your_username/.atom/packages ✓

Unless you have a specific reason to use a different version than the default, uninstall without hesitation.

% apm uninstall archive-view

That’s all from the Gemba, where I checked the list of packages that come with Atom editor by default using the apm list command.
