Comment:
I'm surprised to see that when we added `IndexOperation` and friends we
didn't realize that `AlterTogetherOptionOperation` and friends were
subclassing `ModelOptionOperation` for its `.reduce` operation (which
make us of `references_model` to implement what you're after here).
This ticket seems to be about implementing model reference awareness but
we could also implement field reference awareness (`references_field`) not
that we have the machinery to extra field references from expressions (see
`Index.check` for example).
