resonates with the slow and on-going discussion here at MO about an algebraic String 2-group (where we should take $n=2$). Henriques says that the appropriate thing is an extension of an algebraic group $G$ by $K_2$, rather than look for 2-group extensions by $\mathbf{B}U(1)$ (which, due to torsionness of the appropriate cohomology groups, won’t correspond to the thing one gets in the smooth setting).
