Yeah, a keys partition (or a general boot/recovery metadata partition) would be useful for this sort of thing. I regret that we didn't define any standards for that (standardizing on the fastboot protocol and general boot/recovery mechanism worked very well).
In recent years, Nexus devices have been using GPT (which conveniently allow named partitions), but different OEM bootloaders take different approaches to managing this (including forcibly overwriting the partition table if it doesn't match what's expected...)
Being more prescriptive about bootloader behaviour is on my "what to do next time" list.
