I think we may be getting too carried away with this. For the vast
majority of users, they will build Xorg in sequence from Introduction to
Testing. Handling other situations seems to be overkill. Sure, twm may
not be needed, but it really doesn't hurt. When the package needs Xorg,
just saying Xorg should be enough. Which piece(s) is/are not that

I don't think so. The book has had the same general layout since about
2004 and this is really the first time it's come up. Advanced users
should know enough to be able to make changes on their own. If not,
they should just follow the book.
