Realm export and import: clean-up needed?


I’m having a look at the import/export features of a realm in Keycloak. I exported a realm, and was quite surprised by the number of elements available in the file.
So I was wondering if it could make sense to clean-up some elements from the JSON to make it more “light”?
If I compare to OpenShift templates for instance there are elements like metadatas, timestamps, etc that bring no value to the template, so they can be removed.
