Remember, if you have a DevOps Team, then you are absolutely not doing DevOps. Developers should be involved in managing everything about their applications, including infrastructure.
Any sufficiently complicated infrastructure that has uptime requirements and significant revenue associated with it is going to have a DevOps Team (or the equivalent) ultimately responsible for ensuring that things are working. I guess it's possible to turn your entire dev team into part-time DevOps engineers, while still calling them Software Engineers, but I've usually found that doesn't work long-term and causes employee retention issues. It's like saying your company does 'No-Support' because you don't hire Support Engineers, while in fact you've enlisted your Software Engineering team to handle all support requests.
Also, if you're working in a regulated field like Healthcare or Finance, or anything that touches PII, your developers often can't have access to deploy code directly to production. Again, you could maybe work around this in the short-term by turning all developers into developers+devops, but they're different skillsets.
