It's an open invitation to tag abuse: someone will discover that nothing 
breaks if they use this field to hold a readability metric for the book, 
and so they will use it for that, or for something else.

Of course, "tag abuse" is a loaded term. I have seen examples where tag 
abuse delivered superb new functionality in a system at very low cost. 
But perhaps that could have been achieved without tag abuse if the 
designers had had more foresight.
