Support for default class settings without explicitly adding attributes about serde HOT 2 CLOSED

I wouldn't want to do this in AttributeUtils, I think. The "defaults" that AttributeUtils uses are what's defined in the attribute class; I think it's unwise to change that.

It might be possible to do in Serde, but it would likely require cloning the classDef with new values based on some defaults provided to Serde somehow. Given that there's multiple places the classDef is looked up, that could be a challenge.

As a partial workaround, you can easily sub-class ClassSettings yourself and use that. Something like (I didn't test or lint this, just writing it out as an example):

#[\Attribute]
class MyDefaults extends ClassSettings {
      public function __construct(
        bool $includeFieldsByDefault = true,
        array $scopes = [null],
        bool $requireValues = false,
        ?RenamingStrategy $renameWith = null,
    ) {
        parent::__construct($includeFieldsByDefault, $scopes, $requireValues, $renameWith ?? Case::snake_case);
    }
}

#[MyDefaults]
class SerializeMe { ... }

I'm pretty sure that would work. You'd still have to tag every class, but at least you can centralize your defaults and any other overrides you want so it's easier to manage later.

(That same trick should work for Field as well, if you're so inclined.)

Thanks, yeah a custom attribute class is what I'm using for now, which does make things easier. I appreciate the complexity in adding something like this 👍🏻
