Any updates here?

This will unnecessarily install the DoctrineBundle even if one does not want to use the bundle with Doctrine ORM.

[devtronic]

Symfony standard also requires the doctrine-bundle by default https://github.com/symfony/symfony-standard/blob/3.4/composer.json

Is it Instead of this change possible to add a "noop" database service and wire this as the default?

[xabbuh]

The difference is that the composer.json file of the Symfony Standard Edition will be the composer.json file of your application which means that you will be able to modify it according to your needs. You cannot (easily) do the same with the dependencies that are pulled in by one of your dependencies.

Ok, I understand. I'll check if there is another way to solve that problem.

@devtronic i've already created a PR for "noop database service", see #2708. I suggested to make db_driver parameter optional there. May be you will find another way how to solve a problem with doctrine service, they say that my suggestion feels like a hack =)

[XWB]

I agree with @xabbuh, we should not make Doctrine Bundle required.
