About destructuring non-array values, null is a very common case that
allows writing nice readable code.
Here is a dummy example:
if ([$a, $b] = $array[$key] ?? null) { /*...*/ }
Turning this into a warning will have a significant impact for sure.

a deprecation would just make the language a bit less pleasant to use
without any real benefit, unless I missed any other rationale.
If you want to provide default values, then surely:
if ([$a, $b] = $array[$key] ?? [null, null])
makes more sense, especially as this allows you to choice different
defaults for $a and $b.
That's broken, the "if" will always be truthy using this style.
There's nothing wrong with the current code. It doesn't need to be
deprecated.
It seems appropriate to mention the previous (declined) “Destructuring
Coalesce” RFC at this point:
https://wiki.php.net/rfc/destructuring_coalesce. Perhaps it might make
sense to revisit that one?
