Apple doesn’t routinely monitor the discussions. These are mostly user to user discussions.
If you want to, you can send Apple feedback. They won't answer, but at least will know there is a problem or a suggestion for change. If enough people send feedback, it may get the problem/suggested change solved sooner. Pick the closest topic you can find.
