How exactly do you think this differs from a single address getting updated? On a lite client this is nothing, on a full client nothing has changed.
There's a reason nearly every single solution involves an individual address tied to a single public key.
All addresses you create after this initial address are deterministic depending on their position. It's like you add just a number to the first address. But they are all unique otherwise sb. would see these addresses belong to one wallet.
And because they are unique your daemon has to watch or compare incoming transactions with every address you created to monitor payments. I might be wrong, but otherwise how does it work?
