I do not really understand the task to be solved. I could see the benefit of if-statements, if you could get computed values, such as:

div#content { background-image:url(normalImg.gif); }
@if (div#content.computedWidth > 500px) {
  div#content { background-image:url(biggerImg.gif); }


.footer { font-size:0.7em; }
@if (0.7em < 10px) {
  .footer { font-size:10px; }

But what is the use case for questioning versions? Declarations not supported will be ignored anyway, and AFAICS most CSS 3 specific features could not be mimicked with older CSS, without modifications in the HTML code or scripting. (I know I use Conditional comments all the time, but usually not because of unsupported properties, but rather because of implementation differencies.)
