There is an implicit shame in disgrace but faceless entities have no shame. They'll just put out another press release written in corporate newspeak by an LLM and move on withe the plans anyway. This is standard Google behaviour. They do it with Chrome, they do it with Android, they'll keep doing it with all their captive markets. I fear that in practice even having an "advanced flow" will make little difference as some applications will refuse to work if you have it enabled anyway (in the same vein if debugging is enabled, for example).

Nothing about Android is open except the absolutely minimum amount of linux kernel that's required to boot the thing. Then it's blobs and restrictions all the way to the screen.
