Description
This PR reduces the number of DB queries by a few.

object..filter(…)
on the queryset against.all()
actually reduces the number of queries. This is because that queryset in most cases is already consumed. Calling it with.filter(…)
actually fetches the data a second time. Therefore filtering in Python is cheaper, especially if the number of languages never exceeds a significant number.Also read https://docs.djangoproject.com/en/5.0/ref/models/querysets/#values
