If that means messing with peoples fstab config it’s probably a big can of worms.
And as I said when I encountered the issue it only affected one out of multiple disks, so it’s not even a potential “let’s fix an horrible outcome for everyone” situation. Also it settled down after a while to a few MB per minute.
If a fix is coming in 5.16.4 and it doesn’t affect 5.15 LTS imho an intervention does more harm than good. If it was a huge issue we would have heard more about it in the last few weeks.
