Motivation
Proposal
To adopt a policy mandating us to not leave the train paused mid-way over one or more no-deploy days, such as holidays, weekends and other days/weeks of no-deploy time.
By Friday (assuming a regular work week) we must either roll forward or roll back. Weekend incident investigation should never have to deal with a multi-version deployment. Even if the train is not blocked and there simply wasn't time to roll out completely, either rollback or roll forward.
