Can I import newly generated address to Bitcoin core with "importaddress" rescan false, for the watch only purpose?

why do I need to rescan if the address doesn't have any history?

Question: will it trigger the "walletnotify" if it receives new transaction on that address without rescanning.

It does not know it has no history until it completes the rescan.

You can either pass a `false` as extra argument (look up the `importaddress` documentation), or use the more powerful `importmulti` command with a recent birth time.
