GitOps is great, of course, but it's possible to go overboard. Most kubernetes deployments in the wild seem to use argocd or fluxcd where every app deployment results in a new commit.
The shortcomings of storing information in git? It's not queryable, for one. Something like etcd would be better for shorter-lived information like app image version. Second, it doesn't work well with larger codebases where there are multiple writers.
