Density conjecture for regular crystalline points in framed deformation spaces

Let pp be a prime, let nn be a positive integer, let KK be a finite extension of Qp\mathbf{Q}_p, and let ρ:GKGLn(kL)\overline\rho:G_K\to\operatorname{GL}_n(k_L) be a continuous representation as in the Böckle–Juschka conjecture. Let Xρ\mathcal{X}^{\square}_{\overline\rho} be its framed deformation space; a crystalline point is regular when its labeled Hodge–Tate weights are distinct. Regular crystalline density conjecture. The set of regular crystalline points is dense in Xρ\mathcal{X}^{\square}_{\overline\rho}. The conjecture is motivated by the goal of showing that crystalline points are dense in the entire unrestricted local deformation space: regular crystalline points are expected to meet every irreducible component. The source presents this as a conjecture and gives no resolution of it in the supplied text.
