Comment 47 for bug 954352

It's still unclear whether enabling wayland support would cause regressions in GTK. Wayland support isn't a priority for 12.10, and even Fedora doesn't enable the Wayland backend yet. It's after feature freeze so the cost/benefit analysis makes a feature freeze exception being granted for this unlikely.

Seb said that he'd like to check with Matthias Clasen first to see what he thinks about enabling this option, perhaps for 13.04.
