Can we note explicitly in the documentation that it can be done at any point then and the deployment doesn't need to wait until SRE are ready to merge a puppet PR?

No, you can continue deploying extensions. As far as I’m aware this won’t stop you nor impede your work. You just open a pull and then someone who can merge and merge it. It’s not a requirement to get done first before deploying a extension.

Do we seriously want to stop MW engineers deploying new extensions. This is a huge change to @Universal_Omega's work

@Paladox: see P381. Ideally, you turn the vmtouch (daemon) into a systemd service (a type of unit) that will run this script on every puppet run, after which you can restart the systemd service (to pick up new files).
