Privacy review for issue 176

Howdy,

This is my first privacy review, so I wanted to send something in advance
of  the meeting, so folks could let me know what I might be missing.  The
relevant issue is found here:
https://github.com/w3cping/privacy-request/issues/176 .

The set of changes is very small, so I am including it inline here:

   1. Removed special handling of color() fallback system colors, since the
   feature was removed from [CSS-COLOR-4]. (Issue 7007)
   2. Added emulation support for improved testing of forced colors mode.
   (Issue 11824)
   3. Updated the properties that apply in forced colors mode to more
   generically apply to the <color> components of all properties, with
   specific known properties moved to a note. (Issue 11857)
   4. Added font emoji fallback logic for forced colors mode. (Issue 8064)

I concur with the self-review that the only significant change is that the
use of forced colors can now be detected without querying for
forced-colors mode.
None of the other changes appear to change the fingerprinting surface or
expose PII.  Since that is a change in how the data is available to the
observer, rather than a change in what data is available to the observer,
my assessment is that this change requires no additional changes to
maintain privacy equivalent to that available prior to the update.

best regards,

Ted Hardie
