It depends on the system too. My amd64 based router doesn't have microcode in the initramfs but that's OK since microcode is handled by the BIOS (Coreboot). Also I think the microcode's not free to distribute, the CPU on the router is fairly old AMD-for-embedded sort of thing and unfortunately AMD doesn't much care about those. Or cares just enough that some updates have come out for the various security issues of recent years but not enough to make it clear it's free to distribute.
