Yes. And making it even more obvious the extremely well known (now) story of how the researcher that discovered the technique of stablizing the spike in it's pre-fusion conformation with proline substitutions (before being acted on by furin proteases) did so while working with MERS-CoV. It's not even obscure knowledge anymore that MERS had the same furin cleavage site. It's filtered out into public non-expert awareness.
