Donaldson–Frohman–Nicas TQFT identification conjecture

Let ${\cal V}^{DF}$ be Donaldson's TQFT associated with moduli spaces of connections on a non-trivial $SO(3)$ bundle. For $x_1,x_2,\ldots$, define

$$D=\sum_{k\geq 1}{k+1\choose 3}x_k\in{\cal P}^+.$$

Let ${\cal V}^{(D)}$ be the polynomial TQFT associated with $D$. Donaldson–Frohman–Nicas conjecture.

$${\cal V}^{DF}\cong{\cal V}^{(D)}.$$

The source notes that equality already holds on vector spaces and invariants, while the claimed TQFT isomorphism remains the conjectural part.
