+- `emfx(..., lean = <logical>)`. Default value is `FALSE`, but switching to
+`TRUE` will ensure a light return object that strips away data-heavy attributes
+(e.g., copies of the original model). These attributes are unlikely to be needed
+as part of the `emfx()` workflow, so we may change the default to `lean = TRUE`
