It's not that the DAG feature isn't useful to me, the problem is that it has to coexist with a badly engineered version (the stage based model) which should never have been released in the first place. It is better to have GitLab not support CI runners than it is to push something that is so badly engineered. Better to delay that feature for 6 months than to increase the amount of legacy you push downstream to your users.

Also, this is just a single example that I pointed out to outline what I think is a problem with the whole development culture around GitLab, which puts too much focus on releasing early, and too little focus on quality assurance. Of course, you shouldn't spend years perfecting the next release, but you release too many features too early for my taste.
