If you are deleting the organizational data and effectively archiving [1] all the images, keeping only the option for public images to be pulled but not updated... then how will affected maintainers be able to delete their now out of date public images after the 30 day cut-off? You will have to retain enough of the organization data to allow that to happen. Keeping the public images available in an archived state is…
"somewhat irresponsible for the `latest` tag. A `latest` tag that cannot be updated is ... worse than no `latest` tag" What's irresponsible is relying on a "latest" tag for updates.
