Can we add a rule to .php-cs-fixer.dist.php to enforce this?

[Wirone]

Exactly: add the rule, apply, fix PHPStan issues if any occur, forget.

[keradus]

as I was describing somewhere in first of PRs in this style - that's the goal.

yet, we cannot blindly replace foo[] or array<foo> into list<foo>, as sometimes we need to use array<key, foo>. I also do not want to apply array<key-type, foo> (as not giving any more value than array<foo>.

auto-apply here cannot do this, but when we are cleaned-up, enabling the rules can at least prevent new cases

[keradus]

example where blind application would apply wrong type, from very this PR:
https://github.com/PHP-CS-Fixer/PHP-CS-Fixer/pull/7905/files#diff-f0f5829e3bd024ac8f67d5e42dc491600f7bde0a372793a1da755c1549369838R506

PHPStan

as mentioned in previous PR, PHPStan is not detecting this type of issue - list<foo> vs array<string, foo> (assoc array, non-list), unfortunately - proof with falsy commit commit / ci

if you know how to do it, please show the PHPStan failing on the mentioned example
