withExtraAttributes - Return models when value is not set?

[MCKLtech]

I'm using extra attributes to set a flag on a model e.g.

$model->extra_attributes->set('purged', true);
$model->save();

However, if I run this query:

$model->withExtraAttributes("purged", false)->get();

it is only returning models which have these 'purged' extra attributes already set. In other words, I want to return models where purged is false OR has not been set at all.

Is there a way to do this?

Just adding a potential workaround in case anyone comes across this on Google:

$model->where(function($query) {
                    $query->whereNull('extra_attributes->purged')
                        ->orWhere('extra_attributes->purged', false);
                })
                ->get();
