 If you are following the book, it *installs* su.  I presume that
you have some modification to the book to suite the hint.  If
everything in your system is only linked against libraries in /lib
and /usr/lib, then the obvious downside is your password storage.
OTOH, if your modification means you rely on libraries in /tools/lib
then your system will be incomplete (broken, at least if you don't
extend $PATH) when you boot it.

 Ultimately, it's your system, so you might need to do some
evaluation to find out what the downside is to *not* following the
book.  I remember that, from time to time, people suggest we don't
actually *need* the autotools - it all depends on what you are going
to do with the new LFS system.  In my case, I've been playing with
newer desktop versions and definitely needed them to overcome
problems.  In a very-limited case you *might* manage to defer
installing shadow, but why take the risk ?

 The more general answer is "FBBG".
