Still needs an antenna tuned to the RFID frequency which will be much larger than the chip. It's cool engineering but doesn't mean you can have a working sub-mm tag.

No, but the chip does usually put a cap on the thinness of the whole assembly (e.g. for cards). This means you can have a paper-thin NFC sticker (which we have now, I guess).

The chip is still the majority of the cost of the inlay, so making a smaller chip is the key to driving total down and unlocking new use cases.
