	Meta was a pure Linux infra shop when I was there in 2018 and the Meta -> GitHub sync process didn’t run their CI/CD process, so future releases might not be as frictionless as the current ones. We might need to push some CI support back upstream and hope things don’t break too horribly…
	Just some food for thought.
