English DID have the formal and informal versions of second person address, it simply evolved out of modern use. Some churches maintain the old thee/thou usage in services (my own has 2 versions a more modern one and that traditional one).
In Russian, the distinction remains in modern use. The formal 'you' is also the plural.
