Comment (by Vladimiroff):
The reason behind this is that `subclassa` (in the given example) is not
technically a **field**. Which means it won't be returned by
`Base._meta.get_concrete_fields_with_model`. The only solution I could
think of is creating `get_all_concrete_fields_with_model` (which should
use `get_all_field_names` instead of `local_fields`).
Anyone with better ideas?
