It's a pre-emptive disclaimer "I know this isn't objective, don't complain about that". And it tells you that the guide isn't going to offer you confusing choices, it's going to tell you one way to do things. For some people that's an advantage.

Thanks for your reply lmm. I can see what you mean. However, I do think it has a high risk of building new dogmas without the understanding of when these dogmas should be broken.
