,Anthony Morris and Ibrahim Karahan, maybe they can shed some lights on the topic.
it’s wrong that you have a single APK file when installing an app using app-bundle.
I completely understand you, to improve the storage consumption they made it harder to share apk files across other devices and delegated the process of managing apk file to the to the Play Store. Having only one apk file contradicts the initial idea of App Bundle, that is to save storage for things that you’re not going to need in your device.
