I was the original author of the cloudflare-go library (which I worked on in my spare time while working at Cloudflare), and I included a `flarectl` command with it, but sadly it didn't get much traction :-(
The short answer is "yes" due to the way the configuration management works. Other infrastructure changes or service upgrades might get undone, but it's possible. Or otherwise revert the commit that introduced the package bump with the new code and force that to rollout everywhere rather than waiting for progressive rollout.
There shouldn't be much chance of bringing the system to a novel state because configuration management will largely put things into the correct state. (Where that doesn't work is if CM previously created files, it won't delete them unless explicitly told to do so.)

Hi, that's me! There were definitely a lot of fun conversations.
I liked that a culture of internal blogs became a thing too. It was good to see people brain dumping their experiments and findings. I think people learnt a lot from following all the internal blogs.
