What the consultation says is that having PPC, open offers for sale or large potrfolios does not "necesarily" make a registration abusive/the registrant a cybersquatter. That's quite a different thing from explicitly making that business model acceptable.
Put it another way, if one said that speeding, drink driving and having no insurance did not "necessarily" mean you should be banned from driving - would you take that to mean that such conduct was endorsed by the legal system. The answer is of course no - and the question may simply be turned on it's head to say "these things do not "necessarily" mean he's a cybersquatter, but they are indications we have to consider as evidence that he may well be".
I suspect even if that passage makes it into the DRS and is read as one might hope, it will have as much weight as 3(b) does now - that non use of a domain is not "in itself" evidence of an Abusive Registration. It won't save you if the Expert wants to transfer the domain and there is a world of difference from saying non use (or PPC use, or for sale use, or warehousing use) is a bar to a claim of abusive registration.
