There was already an option for a very long time, and in fact Mint had already changed the default since a long time ago (see e.g. https://forums.linuxmint.com/viewtopic.php?p=1572457).

Changing the default is the point, because people often just don't look into whether it's possible to configure things. They might not even get the idea that the asterisk feedback could be possible, or useful, until it's shown to them.
