There was always one reason: limited memory bandwidth. You simply couldn't cram enough pins and traces for all the processor io plus a memory bus wide enough to feed a powerful GPU. (at least not in a reasonable price)

We solved that almost a decade ago now with HBM. Sure, the latencies aren't amazing, but the power consumption numbers are and large caches can hide the higher access latencies pretty well in almost all cases.

PS4 / PS5 / XBox One / XBox Series X are all iGPU but with good memory bandwidths.

Only time that I can remember HBM being used with some kind of integrated graphics was strange Intel NUC with Vega GPU and IIRC correctly they were on the same die.

That product had an Intel CPU and AMD GPU connected via PCIe on the same package, not the same die. It was a neat experiment, but it was really just a packaging trick.
