I agree. I think the grandparent is maybe describing an ideal state, but in practice most "DevOps" and "SRE" positions I see go by on job boards are for either sysadmins who can do some automation and infrastructure as code, or possibly devs who know how cloud infrastructure and networking work, depending on your perspective. If you're lucky the hiring manager might have at least read the Phoenix Project or the Google SRE books.
