As pointed out by Nevin: A use of std::launder that does not make use of its return value is always pointless; the function has no side effects.
Priority 3; Nico's upcoming paper P0532 should address this and other issues around launder.
This should be handled post-C++17 by Nico's paper P0600.
This was resolved by the adoption of P0600R1.
