How to handle deleted source repos

Something interesting has just popped up via a colleague - the package https://pypi.org/project/cron-schedule-triggers/ has deleted the underlying source repo https://gitlab.com/dameon.andersen/cstriggers

What's the best way of this being surfaced via the API? (If it's not already, that is!)

Start by examining the API response for the PyPI package cron-schedule-triggers and how its GitLab source repository is represented. Compare the available metadata with the deleted repository case described in the issue, then define what API signal or representation should indicate that the source is no longer available.
