Comment:
The auto-detector has to be adapted to make the `AddField` of generated
field depend on any other `AddField` or `AlterField` of field it
references through `.expression`. Since `GeneratedField` cannot depend on
other `GeneratedField` the easier way of doing to avoid introspecting
`.expression` is likely to make them depend on all other
non-`GeneratedField` fields being added per model so they are always last.
