I wouldn't be surprised -- it's a gaping hole for anticheat software if not addressed. In fact, long term the anticheat is going to have to require a completely locked-down (console-like) experience from boot firmware (ME/PSP attested) through OS and userspace, or it will not be effective.
Which is one reason why I don't rent games on Steam, and why I bought a PS4 instead. If I'm going to have to game on a completely locked down system, I vastly prefer to do it on a system that doesn't touch any of my personal data and for which I can still buy permanent, resalable (and yes, even lendable) games on physical media.
PC gaming hasn't interested me since Steam on Windows with mandatory anticheat became the primary way to play games.
