You all need to work together to come up with a unified place for
this and stop making it platform-specific.

We're talking about things that have massively different semantics. How 
do we expose that without an unwieldy API that has to try to be a 
superset of everything implemented, which then has to be extended when 
yet another implementation shows up with another behavioural quirk? EFI 
variables already need extremely careful handling to avoid rm -rf /sys 
bricking the system - should we impose that on everything, or should we 
allow the underlying implementation to leak through in some ways?
