Comment (by amit):
Very cool work on font fingerprinting defenses. I have a question with
regards to the following statement:
> It does not prevent an attacker from identifying the operating system,
nor from distinguishing two versions of an operating system by detecting
different variants of the same font.
Does this mean that the forcing the platform to `Win32` the cpu-class to
`Windows NT 6.1`, and the user-agent to have `Windows NT 6.1` does not
help increase the size of the anonymity set (mentioned in #9501), since
the fonts allow distinguishing between Windows, MacOS, and Linux in any
case?
