IMHO, bluetooth is definitely not a core system for a desktop/laptop. Experience has taught me the bluetooth rune is an ancient symbol that means probably might work. There's no reason I would purchase a bluetooth perhipheral when a wired equivalent is available.
For a mobile phone, it's probably a core system; connecting to a car radio is an important use case. If wired android auto/car play includes hands free calling over usb, then that could be enough, and maybe bluetooth can be relegated to my history bin; but a lot of people like wireless earbuds.
As for WPA3, I dunno? Afaik, I've never needed that either, but my wifi is a bit old.
