It won't make much difference actually at start-up as the valve is cycled through open / close every time anyway. That makes sure that the valve doesn't get clogged up for those who always drive with it closed (or, I guess, in the same position). The double tap on the flag button is complete before the valve cycle is done. Removing the valve is an option, locking it in one position might mean that it gets stuck there.
It might be that if this cycle is not completed (how would that be detected?) then a fault is generated.
