The spec requires the driver to update the Client documentation:

• Document that auto encryption is an enterprise-only feature
• Document that auto encryption only occurs on collection-level operations
• Document that auto encryption requires the authenticated user to have the listCollections privilege action
• Document that a local schema is more secure
• Document that a local schema only applies to client side encryption, and specifying JSON Schema features unrelated to encryption will result in error
• Document that the user is supposed to use ClientEncryption of auto encryption fails
• Document performance limitation: Enabling Client Side Encryption reduces the maximum document and message size (using a maxBsonObjectSize of 2MiB and maxMessageSizeBytes of 6MB) and may have a negative performance impact.
