>to a truly secure desktop is librebooting a cpu, which only works on certain (usually old) cpus and risks permanently bricking them if done wrong.
Libreboot is installed on the BIOS SPI flash chip on the motherboard and not the CPU.

Where did you get the "permanently bricking" part from?
If you flash a bad BIOS image, fixing such brick consists of attacking an external SPI flasher to the SPI BIOS chip and flashing a known good image (you should always have an external flasher, but even internal BIOS flashing isn't that risky).
