I can see where your generalisation is coming from, but again, it's a generalisation. There are a bunch of nice layers that build cleanly with Linus's tree against OE master no problems. That takes work, naturally. In one of the Yocto Summits I've been to there was literally a talk about "stop venturing the kernel". Everyone hates it. We really do fight against the major SoC vendors to stop not upstreaming stuff and it has been getting better :-)
