Internal Comment Prevents Suggested Replies

It appears that an internal comment deactivates suggested replies.  This is problematic because of years of automatons that include private comments to alert agents to conditions when tickets are created.   Private comments are also added if the ticket needs to be escalated to another group.   It makes perfect sense to disable suggested replies once there is a public reply to the End User but I don't see values in disabling this based on Private comments.

If this was intentional, I'd love to understand the rationale that I am not considering.
