comment Grothendieck -sad news
@Guidi: I think he discusses this with Serre in their correspondence (it should have been trabslated). He also mentions it in "Recoltes et Semailles" (only available in french, I'm afraid).

It is fine with me to close it, as this is not a real question. I think everybody got the information, so there is no need to keep it up.

comment Is there a “by hand” proof on the symmetry of the Atiyah class of $TX$?
Well, there is a by-hand (and differential geometric) proof in the paper of Roberts and Willerton that you cite. It is not on page 29 (where they explain Kapranov's proof) but earlier on page 14. They do it very explicitely (see my answer below).
