Well, I don’t know… In parts, it already points worries about risk surface
And risk surface worries is a given for every softfork BIP, not special to covenants BIP. When you read a softfork BIP, risk surface must be something you are thinking of. CAT is a rather different opcode, even though it implements similar use cases, it may seem kinda awkward to point it in this BIP.
But I think APO is significant to be cited.
