Sure. When people are sure that KMS actually handles all the cases that old X does (maybe that's true now), and we've had more than just a couple of kernel releases of _stable_ Intel KMS, I suspect we can start thinking about "ok, nobody seriously uses 3D on Intel integrated graphics _and_ updates the kernel". The fact that they'd still have a working X setup would make it generally much more palatable, I think. But we definitely need more than just a couple of kernel releases. So we're talking timescales of "more than a year of stable code". Whether that is "six months from now" or "two years from now", I can't judge. And people can try to convince me to be more or less aggressive about it, so take the above as a more of a personal opinion that is open to change than anything definite and final.
