@AndrewDudzik: the $U$ is always open as a rigid analytic subspace of $X_\eta^{an}$.

comment Do all curves have Néron models
With Jilong Tong, we actually proved that the Néron model of any smooth projective geometrically connected curve of positive genus exists, and is equal to the smooth locus of the minimal proper regular model.

comment Absorbing ramification and factoring finite flat maps
Each $Y_i$ is given by the subextension $K(Y_i)$ of $K(X)/K(Y)$. As $K(X)$ is finite separable over $K(Y)$, there are only finitely many subextensions.
