The root .model.json is getting rendered by ComponentExporter. This is different than normal jackson exporter. So, the business logic can go intogetExportedType() that is in each sling model. if we return NULL from here instead of resource type, the component do not renders on Front End.This would r...

But the spa project uses spa core component at "com.adobe.aem.spa.project.core.models.Page". This is not public, so can not even get the file and over-ride it.

1. How caching works with SSR ? Looks like, with SSR enabled, the model json should not be cached and same goes with page. Because,  all pages have CUG based components.2.
