Every engineer I meet advocates for standards. Usually the more dogmatic ones are the worse ones. This doesn't make you a 10x force multiplier (telling people to lint makes them 2% more productive tops). Usually these "standards" people though have a negative effect because they get into a dick-contest over the most trivial details (e.g. tabs/spaces).
Even if cross-team collaboration-roles are important, what makes them a step "above" a senior engineer? If the skillset has no relation to problem-solving, it really isn't an engineering role.
What ACTUALLY happens is companies like pretty hierarchies at a 10:1 ratio. They like these hierarchies regardless of the distribution of skill, and the titles rarely align with the skill. Then they come up with a bunch of buzzwords as they grow until they succeed like uber/twitter at losing a billion dollars a year and go out of business.
