I think non-associativity is safest, because even if it's rarely desirable, code may be out there that works accidentally with the current situation. There's also the risk that someone would get used to it working one way in PHP 8, and accidentally use it in code that's still deployed on PHP 7. In both cases, it's better to generate an error and force users to be explicit than introduce subtle bugs. We can then look at making it right-associative in PHP 9, because anybody that needs to support 7, 8 and 9 can be explicit, and hopefully not many people will be jumping directly between 7 and 9.
