Generic splitting-type conjecture for logarithmic bundles of line arrangements

Let ${\mathcal A}$ and ${\mathcal B}$ be line arrangements with isomorphic intersection lattices

$$L({\mathcal A})\cong L({\mathcal B}).$$

Let $E({\mathcal A})$ and $E({\mathcal B})$ be the associated rank $2$ vector bundles on $\mathbb{P}^2$. For a generic line $L$, the restriction of each bundle splits as a direct sum of two line bundles; this pair is its generic splitting type. Generic splitting-type conjecture. The bundles $E({\mathcal A})$ and $E({\mathcal B})$ have the same generic splitting type. Over $\mathbb{C}$, the source presents this as an equivalent geometric form of the stronger Terao conjecture.
