To be honest, I love beta softwares. I use beta software on every device, even I'd there's stable public software. I love to test early software. I use Windows 11 canary insider preview as well. I wish if phones had same option as Windows. Whether you choose beta or stable, your choice
Theoretically, it might be one more beta and after this the stable version. Or no more beta version and the stable version straight away. It's just my guess.
