It's entirely relevant here. The opinions of a staff engineer on this stuff should be interpreted very differently from the opinions of a developer with much less experience.
Case in point, this person has around around 7 years of professional experience at just two companies, Zendesk and GitHub. I don't mean this as a personal dig in any way (truly) but this simply isn't what we used to mean by a "Staff" level software engineer.
This person is early-mid career, which we used to just call "Software engineer" then "Senior Software Engineer" and now (often enough) "Staff Software Engineer"
Not because of lack of skill, but I don't care. I could ask for a fancier one and most likely get it, but why?
