RaTG13, the mystery of SARS-CoV 2's cousin virus with which it shares 96,2 percent of the genome

On February 3, 2020, an article on the possible origins of the virus is published in the journal Nature, which almost nobody notices, apart from the experts. The Wuhan Institute of Virology announces that it has found a bat virus that shares 96,2 percent of the genome with the new coronavirus: of all known coronaviruses, RaTG13 is the closest to SARS-Cov-2.

Why, given the exceptional nature of the discovery, no other details are provided about the origins of this old virus so similar to the pathogen that killed 900 people worldwide?
