It's not at all specific to Pixels and is a requirement for secure verified boot. Pixels support unlocking and flashing different firmware/OS images along with another OS verified boot public key to the secure element so it's more relevant. It's possible to hard brick a device with unsafe use of fastboot mode commands, but installing another OS can be done safely without it being possible.
