Ternary was made non-associative in 8.0, so it requires parentheses. It will become right-associative in 9.0. But there’s not much use case left for nested ternaries in PHP since the `match` operator was added in 8.0.

To be fair mine and a lot of people's reaction to getting bitten by this was completely avoiding ever using the ternary operator in PHP.

So it became sane as soon as late 2020.
