Really nice project, and really hoping these efforts could make devs lives easier! Alibaba indeed built a OSS project named KubeVela (https://kubevela.io) with similar goal though with a bit different approach:

1. Modeling all platform capabilities with Helm/CUE modules, so essentially a PaaS built with Helm/CUE.

2. Self-service workflow based on above LEGO-style components.

3. No specific add-on system, so just Helm charts.

We also auto-gen forms based on Helm/CUE, it's great more and more products are leveraging this capability and wider ecosystem.
