There are too separate issues: testing clutter itself, and using clutter to test other parts of the graphics stack. Re the former, all you can say after testing cogl/clutter against mesa software rasterizer is that a particular configuration and a particular backend (in oe-core that would be the GLX backend) work with mesa software rasterizer. This says nothing about any other configuration, with any other backend or whether it works with any other GL/GLES implementation. In reality, cogl/clutter need patches to build against the likes of TI's GLES (e.g., Beagleboard) or to work on the likes of RaspberryPi, and these patches cannot be included in oe-core, of course, because oe-core knows nothing of such machines. Then there are little annoyances, like the fact that over the last year or so, clutter has tended to have a dependency on a specific but mostly random versions of libxkbcommon (from what I can gather, determined more then anything by whatever the Fedora packager happened to package and what version of Fedora the clutter maintainer was using), or Clutter's customary insistence on as recent glib as you can get. This can all be nicely encapsulated in small layer. Regarding using clutter to test other parts of the graphics stack, which is what Richard is wanting clutter in oe-core for, this amounts to testing mesa sw rasterizer. There is limited value here, it's the one GL implementation that nobody using Yocto to build images will be deploying for real, so this is a weak argument for needing clutter in oe-core.
