As stated in the README file:

What is cairo
Cairo is a 2D graphics library with support for multiple output
devices. Currently supported output targets include the X Window
System, win32, and image buffers, as well as PDF, PostScript, and SVG
file output. Experimental backends include OpenGL (through glitz),
Quartz, XCB, BeOS, OS/2, and DirectFB.

I think make cairo support GIF output is a good thing to do.
Now GIF patent is expired so more and more applications are coming
back to support GIF. There is no more politic bullshit regarding GIF
anymore. IMO, PNG has better than GIF in compression ratio but PNG
does not support animation. MNG is the future of both GIF and PNG. So
why we limit ourself in just PNG?
