How to enable car routing for military areas?

I see CarFlagEncoder has restrictions for residential, military and private roads.

    public CarFlagEncoder(int speedBits, double speedFactor, int maxTurnCosts) {
        super(speedBits, speedFactor, maxTurnCosts);
        restrictions.addAll(Arrays.asList("motorcar", "motor_vehicle", "vehicle", "access"));
        restrictedValues.add("private");
        restrictedValues.add("agricultural");
        restrictedValues.add("forestry");
        restrictedValues.add("no");
        restrictedValues.add("restricted");
        restrictedValues.add("delivery");
        restrictedValues.add("military");
        restrictedValues.add("emergency");

How can I allow car route in military and residential road using config.yml?

This is currently only possible via the Java source code. But the opposite is possible (further limiting an existing FlagEncoder) via the new customizable routing feature:

How do you suggest by code. Do I have to create new FlagEncoder or is there some other way to grant access to car in case of military and private roads?

I would probably just extend the FlagEncoder, yes. And then maybe call

restrictedValues.remove("military");
// or
restrictedValues.clear();
restrictedValues.add...

?
