Also it was just a recommendation as far as my searching can find, for example https://www.nationalreview.com/news/faa-panel-recommends-cha...
This summary of a 2024 FAA re-authorization has the word 'cockpit' 6 times, so I'm dubious that much was done with that recommendation.
EDIT: Fixed link,

Joke aside, the term comes from the navy, the place where the cockswain/coxswain, the person in charge of a boat, is. Should that post be renamed to flight swain?
If we're going to make such efforts to change words, I think it's time for a new artificial non-ambiguous language as the international standard. That way, we could learn our local dialects, and the common tongue where all the historical warts are corrected. As a bonus, computers would be more efficient with a non-ambiguous natural language.
