I suggest following items to be done before going into release: 1. finish testing and provide test evidence on basic functions 2. integrate with NewImageMounter() method and provide a switch to enable it (use previous implementation by default, use new implantation if user tell us to) 3. squash all commits into one to maintain a clear commit history

Going into alpha branch to meet SoC requirements, please see comment for follow up actions to be merge to main branch and next release.
