I agree with the concept that it is turning into something else, as I see DevOps/SRE/CI/PM people doing QA work through trying to just make the thing go. It just is leaving a lot of gaps in longevity, complex setup, and building tests either manual or automated to do that better. In the last dozen or so teams I've interfaced with this is just getting worse as I'm seeing lots of situations where things like backup/restore breaks from the last hotfix, upgrade a system a few sequential versions, and only covering X-1/X critical features in ordinary testing. These are things that a traditional QA team would cover after it burns the business/org in one way or another, but since it's not a core focus of some of these people covering parts of the same role it's leaving a lot of not-obvious gaps in a lot of groups.
