Looks nice. I guess my question is how easy would it be to implement this into into the providers directly? Reminds me of OPA which I believe does something similar already.
The more complicated thing is that it supports imports and modules. A lot of programs may need some adjustment for this concept. For example, what do you put in a k8s ConfigMap? Should a container have an init step to fetch modules?
Grafana and Sigstore are making Cuelang first class. There are some other CUE native applications developing in the community.
