We've been told the same thing.  I'm inclined to believe it, although I'm
surprised we haven't yet seen yahoo system messages at login about it.

The primary difference is just the login method, which has been reverse
engineered and documented.  It's significantly simpler than previous versions.
I have a patch provided to me by our voice and video SoC student from last year,
but I haven't yet applied it because I'm waiting for our Yahoo SoC student from
last year to sign off on it or commit the code he was already working on.  I was
actually going to e-mail him about it in a week or two.

It's potentially possible that it could have been used as a reference, but it's
not really necessary to do so, as I explained above.
