@kinke created dlang/phobos pull request #8358 "Work around issue 22619 - Avoid
Nullable copy ctor unless required" mentioning this issue:

- Work around issue 22619 - Avoid Nullable copy ctor unless required

  Copy ctors are still buggy, so unconditionally adding one for Nullable
  is everything but a non-breaking change (and was added in the 2.098.1
  point release).
