"Be aware that inclusion in the preload list cannot really be undone. You can request to be removed, but it will take months for the deleted entry to reach users with a Chrome update and we cannot make guarantees about other browser vendors."<p>So basically once you submit it your domain is forever HTTPS on Chrome? I'm sure there are cases that might warrant HTTP. Mostly though the cases I am coming up with are mostly testing or implementation speed. It is generally easier to stand up HTTP than HTTPS. At least for now until Lets Encrypt is standard.
