What Would a Kubernetes 2.0 Look Like
The desired package management system they describe sounds a lot like Carvel's kapp-controller (https://carvel.dev/kapp-controller/). The Carvel ecosystem, which includes its own YAML templating tool called 'ytt', isn't the most user friendly in my experience and can feel a bit over-engineered. But it does get the idea of Kubernetes-native package management using CRDs mostly right.

Helm is both "package manager" and "templating engine" - probably the best package manager but horrible template engine
We use kapp-controller when applying our charts (it uses helm template instead of helm install) so we can be very rigorous about what fields are changeable (like through pod autoscaling) and what are not (securitycontext, etc.)

How to handle the lifecycle of multiple COTS
Even further, you could describe your "fetch", "template", and "deploy" stages in akapp-controller AppCR and then you'd have a controller (like an operator) running the cluster continuously reconciling your private cloud to ensure that it's always reconverging to the desired state. This is basically what's underpinning a number of VMWare's commercial (and OSS) Tanzu offerings, as well as some other organization's internal platforms, or "self hosted private clouds"

ArgoCD vs. crossplane-helm provider for managing helm releases?
Full disclosure: I work on https://carvel.dev/kapp-controller/ which can also continuously reconcile helm charts (via our own CRD ).
