The Deletion of Docker.io/Bitnami

Anyone know what happens to their Helm charts? As far as I know they remain available but do they work with non-Bitnami images? Can I use the official redis image instead of bitnami/redis with the Bitnami redis chart for example?

This is covered in the official GitHub issue: https://github.com/bitnami/charts/issues/35164

Q: What will happen to the existing OCI Helm charts? A: The already packaged Helm charts will remain available at docker.io/bitnamicharts as OCI artifacts, but they will no longer receive updates. Deploying these charts will not work out-of-the-box unless you override the bundled images with valid ones. *except for the BSI images included in the free community-tier subset.

That’s the first part, but will the charts work if I override the image name with a non-Bitnami one (e.g. docker.io/library/redis for redis)? Or do they bake in special stuff in their images that their charts rely on?
