Enhancing information_schema.global_variables

Would it be possible to add the following 2 columns in tie information_schema.global_variables table :
1. a column which indicate wether the status variable is dynamic or not
2. a column which indicates wether the actual value is default, inherited from config file or changed through set global command

the first one is purely indicative, so very not important, but the second one could defintly help with configuration management and would comes in handy.
