Loday's conjecture on Leibniz homology of the linear group

Let $R$ be a unital associative ring and let $\mathrm{GL}(R)$ denote its infinite linear group. Write $\mathrm{HL}_{\bullet}(\mathrm{GL}(R),\Bbbk)$ for the Leibniz homology of this group. Loday's conjecture. The Leibniz homology of the linear group $\mathrm{GL}(R)$ is provided with a connected coZinbiel-associative bialgebra structure. This is the group-level counterpart of the coZinbiel-associative bialgebra structure appearing for Leibniz homology of matrix Lie algebras; the supplied text gives no evidence that the conjecture has been resolved.
