Cutting core size and saving just a few mm^2 per chip means a few more chips per wafer which is critical to the bottom line given the radical price increases for each node.
The only company this doesn't seem to be particularly true for is Apple.
Apple has 2 large, high-performance cores, 4 relatively large efficiency cores (around A78 performance levels), a large GPU, and a whopping 32MB of SLC (system level cache).
Meanwhile, Qualcomm's just released Snapdragon has ONE high-performance core (that is still smaller than Apple's performance cores) and 3 "medium" cores that are only a bit better than Apple's efficiency cores with a smaller GPU and a tiny 6MB SLC. Qualcomm has been so desperate to lower wafer/chip costs that they even moved to a terrible Samsung process.
The only specialized units are HIGHLY specialized. They are fixed function (or near fixed function) video decoders or ML units and none of these actually add very much die area. GPUs have actually moved heavily toward general purpose computing (GP-GPU) specifically so they could reuse the die area for other non-graphics things.
