Hi Leigh,

You should be happy to know that as a follow up to your email, an issue 
[Issue-42] was formally raised and closed with the following resolution:

"remove section 4.8 from the ldp spec and move it to the deployment guide 
- it is a best practice "

[Issue-42] https://www.w3.org/2012/ldp/track/issues/42

Thanks for your feedback.
