We cannot retrofit these qualifications onto what have always been arbitrary titles, just because it sounds plausible. Imagine you are reading a candidate's resume. At one past job they were called "Software Engineer" and at another they were called "Software Developer". Nobody would presume to say to the candidate, "So, I see you did rigorous development with proper quality controls and metrics at Company A, but you did move-fast-break-things development at Company B?" You can't infer that from the job title, because the title is just whatever each company feels like calling programmers.
