Patent issues.

But: which UAs do not support GIFs yet do support enough of (X)HTML and 
CSS that they will be relevant when showing interoperability of CSS2.1?

(Note that our exit criteria excludes UAs that are not "intended for a 
wide audience" and that could not "be used on a daily basis".)

The simplest compromise from my point of view would be to make the 1x1 
transparent image (the only image that is likely to cause WinIE any 
trouble) a GIF, and the rest PNGs. Or to make the 1x1 image both GIF and 
PNG and use HTTP content negotiation to serve one or the other depending 
on what the UA claims to support. (But bugs in WinIE's HTTP implementation 
may make that self-defeating.)
