I assume Intel's "microcode" updates include the PCU code, maybe some ME code, and whatever other little cores are hiding in the chip.

When I look at a "BIOS update" it usually seems to include UEFI, peripheral option ROMs, ME updates, and microcode. So if the PCU is getting patched I would think of it as a BIOS update. I think the ergonomics will be indistinguishable for end users.
