Well its not in Emacs 21.2. I don't have 21.1 but I doubt that it has it.
Looking at the ChangeLog it seems to have just missed the branch from which
21.2 and 21.3 were also released.

So at three and a half, defvaralias must be about the oldest feature still
in CVS!

I think the NEWS entry is correct.
