Agreed. Henceforth corrected because I didn't really want to go there.

You got exactly what I meant. I also think Terry's suggestion of
stability levels can easily be encoded in metadata in the yum repo, if
anyone wanted to do that. Then it could dynamically change as people
voted in Bodhi, and I could set a threshold of something awesomely high
for applying updates, or say "wait until it's a week old first" :)
