And an additional educational question 🤓 If I use a a block for infrastructure (like kubernetes-job) - then execute ``prefect deployment build`` using this block - does the deployment somehow have a link to this block? Meaning, if I change something in the block after creation of a deployment, is this reflected in next flow run of this deployment?

Yup! Infrastructure is checked at runtime. When your agent goes to start your flow, it will pull your infrastructure configuration from your saved block settings. So whatever your block settings are at the time of starting the flow, are the settings used by the flow run
