How to persist state if the default state has not changed?

[GeoffreyHayward]

How do I persist the state of a store if the initial default state has not changed? If the defaults are accepted, I don't need to ask for the user's preferences for another 365 days. But I must get the user to accept the defaults before using them.

I am creating a store that starts with everything given a default value. If a user changes any default values, it saves the store to a cookie. However, if the user accepts the default values without changing anything and presses an 'agree' button, the store’s state does not get saved into a cookie. No cookie is created.

I looked at the source and found updateStorage and wondered if that could be used in my component’s agree method. However, updateStorage expects a strategy as its first argument, but I don’t necessarily know the strategy inside a component, and a store could have more than one.
