Why is it silly of the Wuppertal group to approach Sixteen Tons? They seem to know what needs to be done in an eventual patch 1.4 and they are free to do it. It is their choice that they will not release their mod unless they are 100% happy with it, a thing that they cannot be at the moment. Instead of accusing them of being silly, we should thank them for exploring the possibilities for mods in EM4, and move the boundaries for what is and is not possible within a EM4 mod.
