It is true that this is somewhat influenced by how Heroku works, but ConfigMaps and GitOps do not meet the same security and usability requirements as Heroku config/env vars.
If you want secure config storage on Kubernetes, you end up using Secrets, which ends up being key-value like env vars anyway. If you want similar security with Git you need a layer of encryption, which breaks diffs and requires additional tooling. This all leads back to why high-level deployment tools like Heroku were created.
