Why do we need them if they are already bound into service container?

[rkgrep]

To allow all types of injection.

app(WidgetFactory::class);
// ...
class MyService
{
    // the same for controller methods
    public function __construct(WidgetFactory $widgets)
    {
        //...
    }
}
app(MyService::class);
// ...

This is gonna work fine in all current 5.* releases, isn't it?

I'm a little bit concerned about BC, because i want to support L5.0 as long as possible.

[rkgrep]

Yes, it will.
You may split code, compatible with 5.0 into a separate branch.
