Comment (by HAMA Barhamou):
I agree with Simon on clarifying the issue and defining a clear interface
before pursuing composite field implementation. Here are some concrete
proposals:
Let's define a minimal prototype for composite primary keys using existing
fields as arguments.
We can then gradually expand to other use cases.
It would be useful to gather concrete examples of users who would need
composite fields before starting development.
Although my schedule has been busy lately and my level with Django is
limited, I'm open to exploring this idea.

use case.

straightforward task I think. `CompositeField` could accept fields as
arguments (not only field names).
