concat-in-order behaviour is more similar to the original auto_combine, but
I don't know.

It seems to me like it depends on the quality of user's data: if they have
high-quality datasets which already have sensible coordinates for each
dimension then' by_coords' is best, but if their data is more primitive
without coordinates (like mine happens to be) then 'nested' is the most
natural default. So do we have a sense of what the largest number of users
would find most natural? Or is this not a good way to think about it?
