Comment:

Thank you Simon
Confirmed that adding `related_name="items"` and calling
`refresh_from_db(fields=["items"])` doesn't crash


> Changing ForeignObjectRel.name to default to .accessor_name is tempting
here but that would likely break tons of things.

As this can be resolved on the model level, I will close this as wontfix
for now.
If we receive a non-invasive fix to support this, I think we would be open
to accepting a patch
