I said what I find unforgivable parsing above,
as it is clearly an unary minus,
I repeat it here:

let  r2 = 0 + -2 ^ 2; // -2;

I'm not in the least interested in justifying choices on demand.

If that were the case they obviously failed.

Methinks your guess is wrong, as the ECMA262 committee should go for 
symplicity, logic and consistency, not for avoiding arguments.

After all, what is wrong with arguments, unless you are indoctrinated from 
childhood that that is against some deity's will?
