Bear in mind that actual features are NOT going away, it's just the web-based UI that has been removed with `mc` command staying intact.
To many of us, having a UI is an actual feature, in so much that if there are alternatives to MinIO that comes with a UI, I'd probably move to that.
I can see an individual or very small team using the web based GUI, but a large enterprise client would need automation that's done via the cli.
