I've never seen this pattern before and I don't know why I always assumed this to be wrong.

You use a getter at the root of the CardDef and you use @model.formattedDatePublished to access the model value. This is great bcos you can share these across formats. But, is this different than a computed or not -- do you know? Typically, all my getters exist on the format template.

In general, this is not a change request. Just a curiosity. I thought perhaps the types will fail or something

I'm unsure if this is the correct pattern or not. However, it works, and I notice the same pattern in a few cards, such as catalog-entry and leaflet-gtfs. Are you referring to a computed field? This is different from a computed field.
