That makes sense, but I think constant latitude, in particular, is a special case that people often have in mind.

The other methods are about defining different meanings of what "going around" actually is while constant latitude is a special case of many such methods, e.g. great circle, not a new definition of what going that way means.

I'm not sure what you mean, but a circle of constant latitude is definitely not a great circle (except on the equator).

You're 100% right, I conflated great circle and small circle there.
