For instance, the following code is safe, useful, and readable:

I myself am not planning to hold a vote on undefined array.
If there were one it would be an independent vote the same as "Undefined
Array Index" in https://wiki.php.net/rfc/engine_warnings which promoted
it to warning in 8.0.
As it's marked as a warning, I would expect it to still get upgraded at
some point in PHPs lifetime, maybe even in PHP 9, but I am not proposing
it with this batch of updates.
