emailAddress of users in REST API responses

Currently, if a user has visibility of email address set to “Only you and admins” in https://id.atlassian.com/manage-profile/profile-and-visibility emailAddress is not returned in REST API responses

The customer would like the following behaviour

• When a Jira admin/site admin calls a REST API endpoint returning user information, the API responses should include the emailAddress of users in the responses
• They would like this to be the case irrespective of the visibility of email address set in https://id.atlassian.com/manage-profile/profile-and-visibility
• Rationale - Jira admin/site admin are able to see the email address information via the UI and therefore should see the same behaviour when using the REST API.
