Notes

This is an API that content can use to request to remain in the background and not be cleaned up. It could accentuate the security concerns of other APIs (for example, an app with Camera permission could be more of a security risk if it can continue recording out of sight of the user), but it is not a security risk itself. It should be noted in the App Review Policy about this fact for reviewers to keep in mind.
