It's odd that you would bump a 5 year old thread to complain and state your justification for why some missing feature is a disqualifying knock against OpenWrt. What's also odd is that you haven't explained what "scan" button you expect to see that is apparently a basic feature of other firmware... I'm not sure you're looking for the same thing as the OP was.
That said, this thread is so old as to be now irrelevant. so I will be closing it. If there is something you actually wish to achieve (other than simply hating on this project), I would suggest that you open a new thread with some specific questions along with a description of your goals.
