array<int|string, ...> Is INT needed for an empty array? Otherwise, it is optional - it is unlikely that it will ever be a list.

[michalsn]

I don't feel strong with these rules at all, but PHPStan infers int|string when you write something like:

'after' => [
    'foo' => ['except' => ['api/*']],
    'bar', // <- this is an indexed element with key 0
],

So in this case int is required.

Maybe there is a better way to solve this.

[neznaika0]

Okay, don't strain yourself. It is for filters that string keys should be used, but not int => string.
