One of the reasons so many users don't do more "real" tests on their
actual production machine (with its much larger variety of packages and
user-customizations) is due to the very real danger of this breaking things.
So, they wait until the actual release, when we say it's safer.
It would be much nicer if it was really easy to copy your current
machine into a VM. This isn't just for generating more QA though -
having such a testbed would be an ideal way to demo an upgrade as part
of a much larger migration as well.
While this would be nice, we still wouldn't catch some bugs - notably,
hardware regressions that the VM doesn't properly emulate.
