Why do root aggregates not show up in REST API calls?

• The REST API is designed to only expose non-root aggregates for all methods (GET, POST, PATCH, and DELETE) and non-remote aggregates in Metroclusters.
• This design consideration was implemented to enforce best practices for managing root aggregates: The configuration or content of the root aggregates and volumes should not be modified: Rules governing node root volumes and root aggregates
• However, REST endpoint /api/storage/aggregates is able to retrieve information of a root aggregate if the root-aggregate UUID is specified in the query:

  ::> set adv

  Warning: These advanced commands are potentially dangerous; use them only when directed to do so by NetApp personnel.
