The OS will discover the variable is non-modifiable when it tried to set it. Won't the current proposal mislead standards compliant use of GetVariable()? For example does it it makes standards compliant code *more* likely to call SetVariable() in order to fix up a variable that it thinks was incorrectly set with the NON_VOLATILE attribute.
Do any existing implementations change variables from non-volatile to volatile?
The UEFI spec is explicit about which variables are volatile and which are not. Simply relaxing non-volatile to volatile in the general case doesn't seem like a useful approach to me.
