[Accepted as a DR at the November, 2023 meeting.]

Consider:

  #include <type_traits>

  template<typename T>
  concept Int = std::is_same_v<T, int>;

  template<typename T>
  concept Float = std::is_same_v<T, float>;

  template<typename T>
  struct Foo {
    Foo() requires Int<T> = default; // #1
    Foo() requires Int<T> || Float<T> = default; // #2
  };

Per the wording, #1 is not eligible for Foo<float>, because the constraints are not satisfied. But #2 also is not eligible, because #1 is more constrained than #2. The intent is that #2 is eligible.
