GitLab is adopting FluxCD as its GitOps engine.
This is process has just started. So, GitLab's own Kubernetes agents remain the same and, according to this article, likely won't be deprecated till 2025. However, the GitOps functionality is transitioned into the maintenance mode.
Also, this article contains the justification behind Flux. Mainly, it was chosen because it fully relies on Kubernetes API, while Argo provides it's own API and UI, which is harder for GitLab folks to integrate into their own product.
