>> Sorry if I wasn't clear. I shouldn't have said media queries, I should have said "CSS property queries". What CSS properties you have doesn't leak any more than your UA I would guess.
>> Unique font names per user seem unnecessary.
As a dev that has worked in CSS for over a decade, I have no idea what either of those mean.
EDIT: I see the unique font names part now, totally missed that while focusing on the other parts.
