is go mod tidy happy with this? just want to make sure github.com/go-openapi/swag won't force up jsonreference or govalidator

[Jefftree]

Yes, go-openapi/swag has no dependencies on either: https://github.com/go-openapi/swag/blob/master/go.mod

[liggitt]

can you dry-run bumping k/k to the results of this to make sure this does what we need?

hack/pin-dependency.sh github.com/kubernetes/kube-openapi=github.com/Jefftree/kube-openapi downgrade-dep

then make sure lint-dependencies and update-vendor are happy, and that govalidator didn't jump?
