Ability To Resend Nonrejected Caves&Cliffs Feedback If Category is Deleted

There are a lot of great suggestions on the Caves & Cliffs feedback category, but I at least, am not aware what will happen to all the feedback posts once 1.17 releases. Will they all get deleted? If so, it would hurt to see a lot of mine & others' good ideas go that didn't make it in the update that also weren't rejected for MC in general. It would be nice for us as a community to be able to resend our Minecraft 1.17 feedback suggestions to their general corresponding categories once the 1.17 feedback category is removed. Or, they could be automatically sent to the general categories so no 1 has to worry about resending them. So people can see & vote on those ideas so that maybe some of them can still come in the future.
