I had no idea there was more to the page because of the weird scrolling on the site, so I missed the glycan (sugar) stuff, which is my bread and butter. I think the consensus is that there is not likely any shielding going on with the glycans (like what you would find with HIV), but there are glycans that stabilise the ACE2 binding part. Also, people have found glycans on a protein cleavage region, which I would expect could impart resistance to cleavage (a predictor I wrote from a few years back correctly predicted those sites).
