Would it be appropriate to re-architecture your extension, so that only the minimal code necessary is in the actual extension? And put the rest into a progressive web app? The way I think of extensions is similar to a device driver for an OS, a way to add functionality that an app needs that isn't already provided by the base platform. This way, you only need to push a new extension update whenever you need new api-level functionality, and you have total control over the rest of the user experience (regular HTML/CSS/javascript). Or would this cause the extension to be rejected by Google, on the grounds that the "api" that it adds would be too open to abuse?
