I agree with the definition but the question what is unimportant is also a
question of opinion

reasons for me to consider book as unimportasnt are the following:
1)not considering the target of winning tournament as an important target
2)thinking that it is possible to improve engine instead of book and get better
results
If shredder9 with book is weaker than some future Shredder19 without book then
it is going to show point 2.

This is only an example.

The idea is clear.
There are many ways to get the opponent out of book without lost position and it
is not hard to find some line to take the opponent out of book with equality or
almost equality with white.

The facts are that as long as the difference between engines is not very big a
book may be important factor in winning tournaments.
