> Most of the things that Rails is "opinionated" about are far more arbitrary than this
To my eye, at least, it isn't a matter of being arbitrary, but rather not having an answer.
PK names don't matter to the machine, so long as everything agrees and modulo illegal values. Humans get massively opinionated, but the machine doesn't care.
Compare with: How long should a query take to run? No, I'm not going to tell you what kind of query, or the size of the dataset, or the hardware at the bottom of the stack, or what the app is actually doing.
It is like asking what specific clothes an arbitrary person should wear.
