There is an effort to make everything hermetic. Namespacing is hard, but not always possible, and touching production servers (and potentially crashing them) could cause significant revenue damage. I don't think all tests should be hermetic - the effort to make such things happen usually do not overweigh the time it takes to do them, but hey - that's what we are doing.
