The WFCO as installed by most manufacturers does perform poorly as most posts indicate. If it is installed close to the batteries with adequate wiring it will indeed perform to its designed specs.
This is the correct answer, except I'd add that if a higher current wfco converter is installed with a smaller battery bank, that will also result in no boost mode. The wfco technique of sensing the voltage after supplying power is IMO a better system than the PD technique of sensing before power is applied. The problem is that it's incompatible with the wimpy converter-to-battery wiring in most RVs, resulting in the "better" technique ending up being worse than the less-better technique. The other problem with wfco converters is their historically high failure rate.
