Either it should be an experimental option, in which case the logic that 
sets the flag on should check that UnlockExperimentalVMOptions is also 
on (else do nothing). (Though this would still be a unusual use-case for 
an experimental option as the intent is that the user chooses to turn 
them on directly.)

Or it should not be an experimental option.

If it is a to be a product flag then it needs to go through the CCC process.
