        private void Test()
        {
            var (name, phone) = person;

            var test = person;

Person

    public class Person
    {
        public string Name;
        public int Phone;
        public string BirthDate;

        public Person(string name, int phone, string birthDate)
        {
            Name = name;
            Phone = phone;
            BirthDate = birthDate;
        }
        public void Deconstruct(out string name, out int phone)
        {
            name = Name;
            phone = Phone;
        }
    }

1. Invoke Refactor This menu on var (name, phone) = person;

Actual result:
"Introduce variable" option is available.

Expected result:
"Introduce variable" option is not available.

NOTE:
If "Introduce variable" refactoring is invoked then uncompilable code is generated:

            var foo = var (name, phone) = person;

If Refactor This menu is invoked on var test = person; then "Introduce variable" option is not available.
