Changing trait provided final protected method to private results in warning

[cs278]

Description

The following code:

<?php

trait MyTrait
{
    final protected function someMethod(): void {}
}

class Test
{
    use MyTrait {
        someMethod as private anotherMethod;
    }
    
    public function __construct()
    {
        $this->anotherMethod();
    }
}

Resulted in this output:

Warning: Private methods cannot be final as they are never overridden by other classes in /in/YtW3h on line 8

But I expected this output instead:

No error

PHP Version

8.3.14 and 8.4.1

Operating System

No response

Not sure I would classify this as a bug, but it makes sense to relax this warning. To clarify, the final modifier is still inherited. /cc @nielsdos, since you implemented GH-13179. Would you agree?

Yeah I think I agree
