Commit 04489eeb02a4 ("ALSA: wm8750: add missing VREF output") added the previously missing VREF widget. And while adding the widget as OUTPUT widget silences the error of the missing widget it should have rather been a VMID widget.
The VREF widget is only used internally as a source for the VREF input of the Out3 Mux. Selecting that input means that the path should be kept powered up at the VREF/VMID voltage, but that there is no actual audio signal. Using a VMID widget will do this, whereas using a OUTPUT widget will simply cause the path to completely power down.
