Dorothy, you have some interesting ideas, not sure if I understand all of it.
As for "you" who do you mean? I certainly did not "want" the sport pilot reg to do anything in the sense you use. I did not create it in any way, I just asked if it is working in the sense that I understand the objective of trying to find a cheaper way to bring new people into aviation.
Maybe you are using the word for the FAA, or in a general sense of the public, it's hard to tell.
As for the ultralights, especially the heavier two place ones used for training, I don't have any axe to grind one way or the other. . I am sorry to see any segment of sport aviation have a set back. I don't know much about them or their safety record or the quality of their training. I have had a few rides at Osh or Sun N Fun, some seemed good, some less so. Some guys took the time to reach out and make friends, but others seem to care very little about the public and stayed mostly in their own clique, unless they could smell a checkbook. I do know when I last visited the small field an runway at the south end at Osh ,it was sparse. In the past I have enjoyed seeing them fly as we come in in the morning.
I think that many student pilots coming into training are not thinking primarily about learning in an ultralight, when they have the idea of becoming a pilot., and they are thinking more of some form of airplane, more like the traditional trainers, but perhaps smaller and newer.Where is the grey area between a two place machine that is kin to a hang glider and the LSA that is closer to a Cub or Cessna?
Apparently you think someone has targeted eliminating 2 place ultralight type trainers. Who would that be? Perhaps the FAA? I think the idea of Sport Pilot came from the EAA, with restrictions from the FAA. I don't know the rationale behind not allowing these 2 place types to be used for paid training. Perhaps they are built to a lower standard or at least the FAA thinks that. Maybe there could be some limited type of training allowed in these, and the student might get something like a special rating that allows them to only fly these types of planes.
I agree that many of these new designs may have more expensive electronics and panels than necessary, but probably market research says that is what sells to the new customer.
