I feel like detecting these environments is directly at odds with user privacy and anti-tracking; but I guess google has never been anti-tracking, so that's not too surprising. Still, I'm incredibly disappointed that they'd essentially require clients be fingerprintable to auth. I feel like this is just codifying an arms race between strengthening requirements and JS environment checks, and hostile embedders ability to emulate a real runtime, and taking legitimate embedders with less incentive to participate in the race down as collateral damage.
