Let's see how many project need a project-specific flag.

This shouldn't be merged just yet. Likely we want to add some changes to a set of projects accompanying this PR. Will do that once we have the restults from the analysis of the projects

Should be fine to rebase and re-run now?

The infra build was passing now, but I can't see the logs, because for me they are either truncated or have a corrupt encoding.
