I followed up with the firmware team on this - and  was told these are 
intended to be internal only methods. They are not something the FW team 
expected to support or to be used by customers. From a Lenovo point of 
view these are not recommended and not supported APIs. Not sure where 
you got the API details from but they probably shouldn't have been 
disclosed :)

Obviously not our call if they get included or not, however they should 
come with a big flag that says "Don't use these unless you know what you 
are doing". Our recommendation is not to include them.

Do let me know if there are some important use cases for these so I can 
go back to the FW team and discuss supporting them properly.

Mark
