In practice
Go back to the person who raised it. Tell them what changed and quote their original feedback so they can place the message.
This isn't the same as publishing release notes. Release notes announce to everyone. A closed loop speaks to the person who asked.
Why it matters for product builders
When customers hear nothing, they learn that feedback disappears. They stop sending it. You don't just lose one comment. You lose everything they might have told you next.
What changes in AI-first products
Drafting the message is now cheap. Checking that it is true still matters. A wrong notification is worse than no notification because it breaks trust directly.
