Why alterations of page properties are not considered a risk and the physmap is? And how would it be easier (i suppose) to attack the latter?
Alterations are certainly a risk but with the physmap the mapping is already there. Find the address and you have access vs. needing to actually modify the properties then do the access. I could also be complete off base on my threat model here so please correct me if I'm wrong. I think your other summaries are good points though and should go in the cover letter.
