Yup, sorry if I haven't been clear, but my intention is to resurrect it in some form in the next months.

I can't use GL on the Raspberry Pi, but some form of software-only composition would be greatly beneficial there to avoid extra copies. In particular we had some incredibly ugly hacks for WK1 which I would like to get rid of. Those hacks made video playback work acceptably on the Raspberry Pi without any accelerated composition: since those hacks cannot apply with the split process model of WebKit2 I would like to provide a proper implementation this time to accomplish the same goal (smooth 720p <video> playback).

As far as I can tell at the moment, TextureMapperImageBuffer provided a good chunk of what I need. I would first aim at enabling it only when ENABLE_OPENGL=OFF, to avoid the issues that lead to its removal. I'm sorry I missed the request for comments when TextureMapperImageBuffer was to be removed, but I was still stuck with WK1 at that point. :(
