No way to check for attribute existence in Eloquent Strict Mode

[levu42]

• Laravel Version: 9.35.1
• PHP Version: 8.1.11

Description:

Imagine a conditional loading of a count in an Eloquent query:

if ($bool) $query = $query->withCount('foo');

Then I want to check in blade whether the count is loaded or not, but in the new Eloquent strict mode, all options I tested threw a MissingAttributeException:

@if($model->foo_count)
@if(isset($model->foo_count))

And some years and Laravel versions back there was a decision made against a hasAttribute method on the HasAttributes trait.

I think this should be reconsidered now, either fixing it so that you can check with isset on the existence of attributes, or include a hasAttribute method.
