I don't think the forum should be changed because one new user with a few posts can't use his tiny screen without clicking on the wrong links. He could get a different device, or change the way he scrolls.
As much as I respect your opinion, I think there is no harm in having a small addition that could be useful for every user since it would provide more convenience and fewer chances of unintentional things happening. The guy I mentioned is a mere reference, the feature can be useful for the forum as a whole, in my opinion.
Asking for confirmation all the time only means people click it without reading, while it's much better to think about your actions before you do them.
You are not wrong about that, but perhaps mistakes and unintentional occurrences are things too, and if there is something we can do to avoid actions being performed that are triggered unintentionally, why not?
