From another comment in this thread:

"The author’s have a paper from March 2019 (in arXiv) that uses the result to build some novel telescope geometries."

Note that "build" doesn't mean they built a physical telescope, they came up with lense shapes.

There are some serious problems when building large telescope lenses; if they get too heavy, they start to deform under their own weight, and non-spherical shapes are hard and expensive to produce.

It would be awesome if this analytical solution inspired improvement in real applications, but I'm cautions about that.
