That's right. Every program nowadays has a book designed specially for it, and a
learning system in order to block the opponent from replaying won games.
The book and the learning are weapons, but everybody has them now, so they just
counter each other and in the end we are back at evaluating real engine
strength. Actually a much better book can make a significant difference, but in
the case of Tiger and Shredder the books have been written by the best authors
you can find, so I don't expect a big difference in quality between them.
The book and the learning system will hurt mainly programs that have a poor book
(or an old one) and no learning at all. That is, it will hurt only older
programs.

That's a good idea, and it would be nice if you could do these kind of tests.
I'm very interested in the results. My guess is that you are going to discover
that the results will be approximately the same than with the standard way of
testing (books ON).
