Not with a singlet -- a single piece of glass. It always took at least two, which is perhaps why lenses of the period used so many cemented doublets and triplets.
What makes this interesting to me is that it can be done with a singlet. Which should allow replacement of a cemented doublet or triplet with a singlet, which should result in a lighter and physically smaller camera lens. Not to mention somewhat better light transmission because of less glass, and less internal reflections because of fewer surfaces, etc. And of course it might be cheaper as well, because less glass even if the singlet is more expensive to make.
So... lighter, smaller, faster, cheaper. What's not to like?
Bottom line for me is that I could hike farther, and make photographs where I could not before. And others like me could do the same. And that, might make it worth doing. IDK.
And lets not leave out the fun of solving an "unsolvable" problem.
