Well that just goes contrary to my understanding of what the main CPU is supposed to do, crunch data, and as much of it efficiently as possible in the smallest package available. TDP rating be damned if it can handle it! If it's dark, it's wasted die space. Specialized hardware that's rarely used (relatively speaking) should resides outside of it via PCIe bus assuming latency and bandwidth considerations are met within the predefined scope of capability and need. Again, just my view on it. And because we're talking about PC CPUs, I don't see why a modern desktop process should be the equivalent of a SoC (System On a Chip). Ergo leaving dark silicon in place as video, wifi, audio, etc. Though for bandwidth and performance reasons, I get why the memory controller is on die. The video, however efficient the Intel HD stuff is, really should be external.
