If GATBY's process out of town was as rough as I've heard it was, and if Chavkin is in a bit of a vulnerable creative state right now, it makes some sense to go with a different director, whether that is Frecknall or someone else...a lot of people could do interesting things with this property. Marianne Elliott, John Tiffany, Michael Arden, Christopher Wheeldon, Justin Peck, George Wolfe, Matthew Warchus, Michael Mayer, etc.
