That text explicitly calls out that adding struct members at the end of 
a struct is considered okay.  But thinking about it now, even adding 
fields to the end of a node struct that extensions allocate using 
makeNode() is an ABI break that is liable to cause all affected 
extensions to break in a crashing way.
