No, I didn't have one. I didn't see it listed as a required dependency.
I've just installed xquarz from the link an Thunar does open it, however its behavior is... there are no icons, whenever the window gets the focus it becomes black... but I think this is not because of Thunar but because of xquarz. I got error like this:
ThunarThumbnailer: Failed to retrieve supported types: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.thumbnails.Thumbnailer1 was not provided by any .service files
