I could easily see browsers using this to allow users to turn support for
various CSS features on and off.  A checkbox for @supports(text-decoration:
blink) jumps out immediately.  A numeric value for @supports(font-size <
4pt) would be very helpful against that particular kind of spam that uses
1px-high text to throw off Bayesian anti-spam tools.  A designer's nightmare
- but a user's paradise.
