I don't think that is necessarily true. If there is a hole in a monovalve diaphragm, enough coolant might be able to get by to heat up both sides but not enough to produce heat.
Unplugging the monovalve might give you heat, but as someone pointed out the other day, it might not if the diaphragm has a tear in it.
Bypassing the monovalve with heater hose shouldn't cause any problems.
