Exactly. It's not about making developers to do more work, it's about having some "DevOps engineer" or Ops/Infra guy working close with the Dev team, by being involved on the day to day development and decision making. Instead of having to open tickets and waiting X time for it to be resolved by the Infra team (who by the way, a lot of time doesn't fully understand the applications, it's constrains, tech debts, needs, etc).
But yes it makes sense to me to still have people specialized in ops and infra in teams, collaborating with developers.
Basically, instead of having developers doing everything or just developing and throwing code out to an ops team, we should have developers educated in operations, working in teams with at least one operation specialist (or "DevOps engineer"). That way, you should end up with infra, deployment workflow that really works for the team and is optimized for the needs of the team.
