Hello @GijsR ,
For “who has what” today, the most reliable alternatives are the system tables and Unity Catalog information schema views, which do include principals. You can use the information_schema to list the current grants the principals (GRANTEE) for catalogs, schemas, tables, views, volumes, etc.These views return identities and privilege types, and the system-level information schema lets you query across the whole metastore.

You can also use the system-level information schema lets you query across the whole metastore.
the system.access.audit table to capture permission-update events and ACL changes (including user_name, group_name, and permission_level) for workspace apps and other securables; this is event-oriented but can be used to reconstruct or monitor permission assignments over time.
