On “I don't trust microcode”
They have been sort of cracked, but it doesn't matter. The web or chain of trust of those updates from the vendor to the processor is what matters. They're at least CRC checked to prevent loading corrupt files.

Westworld - 4x06 "Fidelity" - Post-Episode Discussion
Not to “well aktchually”, but all modern processors do have regularly updated microcode that’s uploaded at boot time - https://github.com/intel/Intel-Linux-Processor-Microcode-Data-Files

My CPU's microcode is missing
6-94-3 would become 6-5E-3. https://github.com/intel/Intel-Linux-Processor-Microcode-Data-Files/blob/6c0c4691e5bb446e0e428ebca595164709c59586/intel-ucode/06-5e-03

amd cpu firmware microcode ? (-current)
OpenBSD kernel has no support for loading microcode on AMD CPUs, A number of issues/errata on AMD systems may be fixed as part of AGESA updates, in addition to microcode as part of BIOS/firmware updates. While there have been microcode updates released for Zen+ or newer CPUs, but these seem to be less frequent than Intel.
- Will you still use Cloudready? Yes/No and why? Please...
- Why is it assumed that microcode updates improve security?

I Love Arch, but GNU Guix Is My New Distro
Is it anymore of a "magic incantation" than the linux-image-XYZ package which controls which OS kernel is installed?

CPU May Have Slowed Down on Wednesday
It isn't clear if Haswell has this optimization. As an easy test you could run the zero-fill-bench linked in the post and check the fill0 vs fill1 numbers. If they are the same, Haswell probably never had this optimization in the first place.
Based on the Intel microcode release note [1] it doesn't seem like client HSW got any update this time, only HSX (Haswell Xeon).
