As far as cat and mouse games go, it's one that's tilted heavily in favor of the Chrome devs. The mice have to advertise themselves very conspicuously in order to gain utility from their workarounds. Cats can usually catch mice that announce themselves. All they have to do is navigate to a site using incognito mode detection and briefly review the code to find the next hole to plug. In this case, probably stop advertising the correct limit for incognito mode, and introduce latencies on writes to mimic a real file system. These are not a trivial fixes, but they also are not hard.
