So.....no, because gamer press is ruthless :P We've had one graphical bug in one of our games(which I'm certain everyone on the internet has seen by this point), and in reality it was only happening if you played on one specific GeForce card, and only when using beta Nvidia drivers. But of course no one cared that the bug only happened when using experimental drivers - it was somehow a proof of how broken our games are. If this(the vulkan backend) lead to any graphical bugs in our games, I can almost guarantee that they would be paraded everywhere, no matter how clearly we mark it as experimental and unfinished.
