It doesn't need controller to be updated, Switch can be updated to have stronger signal for Joy Cons.

To boost the console BT reception range would require delaying the console in the US to undergo FCC certification again.

You dont know that, we dont know what range Nintendo filed for Switch and what range actualy Switch is using, maybe that range from some reasons in some consoles is weaker than in other and that actually causing problems.
