I think that old chessbase book can be a disadvantage because
it is more easy to release a killer book against the old book then to release a
killer book against some unknown book.

I think that the fact that the ssdf test free programs with that book is a clear
encouragament for amateurs to use another book because otherwise there is a risk
that they are going to lose a lot of games by killer lines in the future.

It is also an encouragement for professional to release a book with killer lines
against a lot of lines in the old book because it can help them against more
than one program.
