What a strange way og thinking. I use old or more or less week computers (my most powerful is a Core i with 8 Go RAM) and I use a large amount of automations without problem.
There are certainly things I I can't do now but some with more powerful computer can, but I'll never think about denying a feature that other people could use and not me.
I vote for this feature. When a group is done, it's to have all it's members moved together, whether one is moved by mouse, controller or automation lane.
