How to delete a draft app from play console and publish from different account?

Question

We created an app and uploaded the bundle from dev1 developer account. The app is in draft stage as can be seen in the screenshot below

We created the internal testing track and send the link to 4 friends to install and provide feedback. Later we decided we want to publish/release the app from a different developer account (dev2)

We paused the internal track , uninstalled the app and requested google support to delete the app. However support is saying that as the application has 'install statistics' they cannot delete the application at this time.

Question 1: As per https://support.google.com/googleplay/android-developer/answer/9023647 it should be possible to delete a draft. Am I misunderstanding draft status somehow?

Question 2: Is there something I can do to reset the install statistics. I could not find clear meaning of 'App must have 0 lifetime installs'. From literal meaning it appears if any one installs it even once, then it can never be deleted.

Question 3: If it is not possible to delete the app, is following workaround inline with google's policies

1. We leave the application as is in dev1 account (i.e. not published, internal testing track paused) .
2. We also unhook this version of the application from the back end server.
3. There after we publish the app from a different account (dev2) with new package name.
