Custom icons would also be useful in the case that SimpleMDM's importer chooses the incorrect icon, or if there are other reasons to use an icon not found in the .pkg

So if an application bundle doesn't have a custom icon, a Munki administrator can add one to the Munki repository and assign it themselves so that the item in question does not appear to the end user as a generic package. However, SimpleMDM's Munki implementation does not offer a path to manually upgrade an icon if an installer imported into Munki does not include a useable one.
