Ability to configure View Permissions for Inline Comments

It would be so useful to be able to configure View Permissions for Inline Comments so only certain users (internal staff for example) could view them. Currently, the comments feature is useless for external-facing documentation as no business is going to want their external users/readers to see comments. 

Adding this feature would be so useful for technical documentation that needs to be reviewed by Subject Matter Experts (SMEs) so they can leave feedback/comments on the pages themselves without external users reading them.
