I think they mean Delta V or the potential change in velocity. So it’s saying that a lesbian relationship has the highest potential to travel the furthest.
From that, I can extrapolate that lesbian relationships are the future of space travel and all future astronauts will be in lesbian relationships.
I like the fourth or the last one since it encourages all other error responses to follow a similar standard. That will allow the client to have a reusable error model and error checking.
I’ve had to use APIs where every response was 200 ok with json, 400 bad request with pain text that said unauthorized, or a 500 error that returned an HTML error page. The worst.
