Note that no-one yet has made an improved name suggestion for this thingee that
is discussed in LWG 2743. Unless this happens, I think that the corresponding
trait should match this name and should match the intention of what is tested
here.

If you believe so, please make a corresponding comment to LWG 2743 and convince
people for accepting this revised name.
