I think it was more "I want to write my code without how it ends up packaged or deployed having influence on how I write it", and vice versa.

We definitely don't have that at my job. We have to be conscious of the dev, test, build and production environments when coding. Ops has to be more conscious of what they are deploying than they'd like. It's not that either team doesn't care about the other's work or the big picture.
