StoreOptions parameter needed for both OpenStore and OpenCollection?

[gertcuykens]

Hi, for me it's not clear why both OpenStore and OpenCollection need a StoreOptions parameter? Is there a case to use different StoreOptions for OpenStore and store.OpenCollection? If they need to be the same isn't it safer to only set StoreOptions on theOpenStore call so no bug's can ocurre when StoreOptions get changed between the two calls?

func OpenStoreCollection(dir string, options StoreOptions,
	persistOptions StorePersistOptions) (*Store, Collection, error) {
	store, err := OpenStore(dir, options)
	if err != nil {
		return nil, nil, err
	}

	coll, err := store.OpenCollection(options, persistOptions)
	if err != nil {
		store.Close()
		return nil, nil, err
	}

	return store, coll, nil
}
