CPOs are specified as actual semiregular function objects that can be
copied and constructed freely, so it seems a bit hostile to make them
final/non-addressable? (It's debatable whether the type of a CPO is a
type "specified in the C++ standard library" for which [derivation]/4
would apply.)

This restricts the API of the CPOs and other function objects so they
cannot be misused by deriving from them or taking their addresses.
