you might consider https://github.com/kubernetes/apimachinery/tree/master/pkg/util/yaml or https://github.com/kubernetes-sigs/yaml instead of gopkg.in/yaml.v3 which (links to https://github.com/go-yaml/yaml/tree/v3.0.1 ) hasnt been updated in 3 years

Seem to be decode only?

or https://github.com/kubernetes-sigs/yaml

This one might be interesting. Looks like a wrapper and fork of go-yaml?

instead of gopkg.in/yaml.v3 which (links to https://github.com/go-yaml/yaml/tree/v3.0.1 ) hasnt been updated in 3 years

Is there some particular bug or issue with the current yaml dependency? but yes if there is a more active yaml implementation it would be nice to switch
