Use Case

As a... driver developer
I want... to remove unused code paths
So that... I can reduce the complexity of the API surface we support

User Experience

• `dbName` and `authdb`, two parameters in the public CommandOperation API but meant only for internal use, are marked as deprecated

Dependencies

• authdb and dbName are used by removeUser, which should be marked for deprecation before this work

Risks/Unknowns

• Confirm the non-use of authdb and dbName (beyond the known removeUser path)

Acceptance Criteria

Implementation Requirements

• none

Testing Requirements

• none

Documentation Requirements

• authdb and dbName should be marked as deprecated in public docs

Follow Up Requirements

• Later, at the next major version, remove authdb and dbName
