Symfony version(s) affected

7.3.0

Description

I tried to upgrade a codebase to Symfony 7.3 that contains classes that serve merely as a namespace for utility functions, e.g.:

final readonly class MyUtils
{
    public static function doSomething()
    {
        // some logic
    }

    private function __construct() {}
}

Those classes are not meant to be instantiated and they're not wired anywhere. However, wen I try to perform a service autodiscovery on a namespace that hat classes like that, I now get an error:

Invalid service "Foo\Bar": its constructor must be public. Did you miss configuring a factory or a static constructor? Try using the "#[Autoconfigure(constructor: ...)]" attribute for the latter.

Excluding each and every of these classes from the discovery solves this issue, but I would've expected that this error is not raised unless I actually try to wire one of those classes as a service.

How to reproduce

I'll try to come up with a reproducer soon.
