use Illuminate\Foundation\Application; in Lumen

[nbk-kolyan]

i recently found that Illuminate\Database\Eloquent\Factories\Factory class
uses
use Illuminate\Contracts\Foundation\Application;
which not exists in Lumen projects
This class then used in try - catch block and that's why we don't see error
So in fact application works:

• because in catch block there is returns default 'App' namespace
• but for me - if php file use Class with not exists - its error, even if code catch it. It looks like in
  Use dynamic app namespace in Eloquent Factory instead of static App\ PR

  Taylor forgot about lumen framework

Do you guys thinks that its ok - because app works and no exceptions.
Or we can just use Contract(interface) instead of Concrete Application class?

Btw in all other places in framework there is Illuminate\Contracts\Foundation\Application (var blocks, return type etc) usage
only in tests folder there is concrete Illuminate\Foundation\Application
