The problem is that they're not doing it as a PP benefit. The current version has the impact of favoring some Plats over PPs and maybe some Golds too, although I can't recall whether there have been reports of Golds being offered the Elite Concierge Services. Another aspect is that it's currently just for IIRC USA residents, so that they're now getting upgrades over those with foreign addresses who might have higher status with Marriott or the particular property.
