you can no longer update microcode after the kernel boots (on modern Intel CPUs). It has to happen before you do Cache As Ram in many cases, or you'll get some pretty unpleasant consequences.

Hello! No I haven't. But I've known about the Intel Microcode update idea for about fifteen years. Turns out that the Linux Kernel 2.4.33.2 of course has it, and described the update process. The two responsible for that method have been out of business so to speak for a while now.
But according to that site its still being done. Interesting. I do also know its volatile, in that if the computer gets shutdown and thence turned off, the feature would need to be flashed back onto its CPU and so forth.
