Simon-type conjecture for knot exteriors in rational homology spheres

Let $X$ be a knot exterior in a closed orientable $3$-manifold such that $H_1(X;\mathbf{Q})\cong\mathbf{Q}$. Simon-type knot-exterior conjecture. Then $\pi_1(X)$ surjects onto only finitely many groups $\pi_1(X_i)$, where each $X_i$ is a knot exterior satisfying $H_1(X_i;\mathbf{Q})\cong\mathbf{Q}$. This is presented as another natural extension of Simon's conjecture; the supplied text provides no proof or resolution, so the assertion remains open.
