FWIW, I like this suggestion very much.

Besides the bloat, it will be a more effective way for authors to document
what's common and what's different between rule sets, since they can define a
common group and reference it in conjunction with the specific differences for
any selector.
That is more readable than scanning a file and trying to accumulate the
multiple references to shared subgroupings of rules.

However, you might want to consider some guidelines for location or ordering of
these indirections, since you can have circuitous references. Or you could
limit the levels of indirection.

 p.section { rule( "div.section" ); }
 div.section { rule( "p.section" ); }

Relative references need to be clarified. If div.section {font-size : 10%},
then does p.section use 10% of its parent, or does it gain the calculated value
of div.section's font-size?

Also, I assume this is just a "compile-time" relationship. If I make a change
dynamically with the DOM to div.section, p.section is not updated right?

I think with some clarifications this is a good addition.
