It's slightly better because at that point presumably you've failed auditing standards for many browsers, not just one. We're talking about "you tried to deliberately compromise security and get away with it by deliberately lying to take advantage of the loophole we'd provided you." With proof of that level of malfeasance, especially if it's widespread for new certs, it is plausible that Chrome and Firefox will both remove your certs, with Edge or Safari possibly coming up quickly behind. Presumably all of this would be "we are publicly announcing that we are dropping this CA in a month" to allow graceful switching...
