Could you describe you problem you are solving by suggesting this change? It would be good to understand the problem so that we can implement proper test case for that.

I agree with you that It's probably good idea to use django API for that.

.eg

import strawberry_django
from strawberry_django import auto
from django.contrib.contenttypes.models import ContentType
from django.contrib.auth.models import Permission

@strawberry_django.filters.filter(Permission, lookups=True)
class PermissionFilter:
    id: auto
    name: auto
    content_type: 'ContentTypeFilter'  # available
    codename: auto

@strawberry_django.filters.filter(ContentType, lookups=True)
class ContentTypeFilter:
    permission: 'PermissionFilter' # not available
    id: auto
    app_label: auto
    model: auto
