Agreed. And while I have no problem with the majority of this, patches that mod authors make for free so that their free mods are compatible with paid additions (DLC or otherwise) to a game rarely contribute to the complication (the point of a patch is to make things easier to cohabitate, no?). This part of your rule goes exactly towards further complicating the process and has no logic based on what you say in your post. You'll end up with the opposite of your intention, I believe, with a decline in traffic due to an increase in confusion for users trying to figure out how to get things to play well together, why their free mod's author won't provide a patch, etc.
In my opinion, this part of the new rule is quite poorly thought out and should be quickly reconsidered.
