alt Hacker NewsAdjective order in English is basically that most essential qualities of the object go closest to the head. There are lists out there that try to break this down into categories of adjective ("opinion-size-age-shape-colour-origin-material-purpose"), and to some extent the anglo intuitions on which sorts of properties are more or less essential are not trivial, but it's not as arbitrary as people want to make it out to be.
This. People act like it's a hyper-complicated rule that English speakers magically infer, when in reality, a) other languages do it, and b) it's a much simpler rule (that you've given) which someone overcomplicated.
As a counterexample (in line with your explanation), consider someone snarking on the WallStreetBets forum: "Come on, guys, this is supposed to be Wall Street bets, not Wall Street prudent hedges!" Adjective order changes because the intended significance changes. (Normally it would be "prudent Wall Street hedges".)
Side note: please don't nitpick about whether "Wall Street" is functionally an adjective here. The same thing would happen if the forum had been named "FinancialBets".
