I was a MeeGo user and hobby developer, you don't have to remind me. And you should know that, as I described, it was born with GTK on top (Maemo); when it was rebranded MeeGo it was because they merged it with Intel's Moblin, another GTK-targeting effort, so the innards were very much geared towards GTK to start with.
