Is the recommended way to define a freshness policy for a model still via the config block (per this github discusion https://github.com/dagster-io/dagster/discussions/14477#discussioncomment-6094301), or have things changed since?

for now, yes. we’ll probably add a “get_freshness_policy”/“get_auto_materialize_policy” function in DagsterDbtTranslator as well if you want to do this programmatically

cool, that's probably a good idea, but was just wondering what the correct way to do it is currently
