It's in experimental only, not unstable or testing. That said I'm surprised it hasn't even propmpted discussion on debian-devel (sans [0]). I would've thought that at least enough Debian developers run experimental to have noticed and raise the issue, but no. I thought about starting a thread myself but couldn't be bothered.
