You are referencing the new design of that csst not bonding vs additional bonding right?
Many home inspectors report “gas pipe not bonded” when it actually is.
The pipe is electrically connected to the furnace cabinet via the furnace valve mounting and the branch circuit ground. This is a very poor high resistance bond to ground and has been improved by what is called “additional bonding”.
The new pipe, usually black, may not need “additional bonding” according to the manuf or the code at this time but it is a good idea.
