I don't know if you've just chosen to assume the worst or don't care enough to think about it for more than a second but I've been very clear in all my comments that these are developer-specific machines we are deploying to. It's literally no different from running VMs on your local machine. There is full visibility and feedback, we aren't deploying to Prod or even QA, this is development where each developer has 2 or more boxes owned by them and only them. We also are working with specific custom hardware that our code runs on which is one reason we can't easily do this locally.
To jump in and call that "worst practice" is just lazy and condescending. On top of that, it's completely wrong.
