I'm requesting a standards position on the launch_handler field I've been working on adding to the Web App Manifest (https://www.w3.org/TR/appmanifest/).

This field allows developers to control whether app launches dedupe into existing app instances or not. Explainer: https://github.com/WICG/sw-launch/blob/main/launch_handler.md

Happy to answer any questions.
