Your scheme sounds pretty similar to something like "if I find the house key in my pocket, I instantaneously know that my wife doesn't have it".

That's fine and useful for some things, but as you say it's not fundamentally quantum and it's not what's exciting about this development imo.

What is exciting about this development then? Because afaict this is the same thing.

There are several exciting applications that rely on a source of entangled particles. Super dense coding and quantum teleportation to name a couple. This is a step towards achieving those.
