I think one of the reasons for using Cairo in GTK is so that GTK doesn't 
have to provide a drawing API.

By just using the Cairo API, libraries designed to work with Cairo (such 
as xsvg) should work fine with GTK, and any additions to the Cairo API 
can be taken advantage of immediately, without waiting for a new GTK 
release.  It also means you lose the benefit of using the same API for 
drawing to the screen as well as printer, unless GTK also wraps all the 
printing related stuff in Cairo.

If this can be done as easily and non-intrusively as Owen says, then it 
will mean more users for Cairo and less maintenance work for the GTK
