Retrieving the entire entitlements set is excruciating. Some method of limiting included details should be enabled. For example, we have a common use case where we need to be able to identify all items owned or approved by an individual who has left the company.
For this, I only need name, id, owner, accessRequestConfig.
Time to retrieve this very large set of information could be reduced significantly by offering some means of limiting the payload to only these (or other desired) fields.
As an aside, this common situation is not addressable by search as it must return roles, access profiles, applications, sources, governance groups, entitlements - and perhaps more - both for ownership and approval.
