Anyone considered 'pluck_deep' with a 'Collection'?

Maybe an example is better in this case.

$result = Model::with('relation1.relation2.relation3')->get();

What about when you are interested in all of the entries from 'relation3'?

I'm thinking about a macro with the 'Collection' class.

Collection::macro('pluck_deep', function($arg) {
    
    $relations = explode('.', $arg);
    for ($i = 0; $i < $count; $i++) {
        // ...
    }

});

$result->pluck_deep('relation1.relation2.relation3');

Has someone did this before or has any ideas? Thanks.
