@stevemarshall yeah, I totally buy that. I think the staging environment option is good for when the test suite for an older system just isn't thorough enough to be trustworthy

@simon @stevemarshall the one time I worked on a system that had explicitly designed for a staging system for testing purposes had then (before my time there) also spun out testing, qa, qa2, qa3, etc, all of which showing subtle differences, all of which gave little confidence when a prod deploy happened such that manual QA had to happen AGAIN anyway
