For context my ideal setup has at least 3 environments - prod, qa/testing before release, and dev. With dev being the most likely to break, and the qa/testing for when we need to be absolutely certain that differences between prod and dev aren't masking any bugs.

I do like the idea of "canary versioning" some stuff. It's a bit of a game theory issue isn't it, since we all need prod to work at all times and can't risk a .0, and a major version difference between dev and prod can mask some nasty issues in my experience.
