Thanks for the update!
We usually recommend to use github.com/ory/kratos-go when selfhosting Ory Kratos and github.com/ory/client-go for Ory Network

This would be the equivalent example with client-go: https://www.ory.sh/docs/kratos/sdk/go#create-and-delete-identity

So I would propose to change the SDK back to kratos-client, otherwise great update.
Does this make sense to you as well @aeneasr ?
