The solution does claim to be better along some axes; your statement would seem to imply that you can't work towards a solution to any problem until all of them are solved. That seems like a recipe for never improving anything, no?

It would be like complaining about an agricultural innovation that's projected to reduce starvation, because it doesn't also cure diabetes. I wouldn't want such progress to "just stop" because they're leaving a given problem unsolved.

If something doesn't work, sometimes it's better to try something else. Especially when the only way to see if something is better is to try it.
