But it becomes systemd's job to fix/compensate for hardware bugs if they explicitly access the hardware directly instead of going through the kernel, no?

They do go through the kernel; it asks the kernel "can I use rdrand", and the kernel says "yep, go ahead, it works on this CPU". If that's not true, and it doesn't work on the CPU, then it's the kernel's fault for lying and saying that it does.
