The output of that listing results in scheduled tasks with policy 'oneshot' and some priority (well depending on the input cli call).
Thus ingesting those faster and without manual intervention as we currently do [1]
Example use case (for now is for small forges):
```
swh lister list --lister gitlab \
--priority high \
--policy oneshot \
--db-url postgresql://postgres@localhost:5432/swh-listers \
api_baseurl=https://gitlab.ow2.org/api/v4/
```

[1] along the lines of psql update "the listed tasks with priority to high", then wait for it to finish somehow, and then at some point, remove that priority with psql update yet again... tedious!
