SARS-CoV-2 itself is not a recombinant of any sarbecoviruses detected to date, and its receptor-binding motif, important for specificity to human ACE2 receptors, appears to be an ancestral trait shared with bat viruses and not one acquired recently via recombination.

Exactly, "detected to date". The animal surveillance programs were inadequate at the time of the outbreak and have since been defunded and shutdown altogether.
