 //  1. Add a new enumerator to
 //     `sycl::ext::oneapi::experimental::detail::PropKind` representing the new
 //     property. Increment
-//     `sycl::ext::oneapi::experimental::detail::PropKind::PropKindSize`
-//  2. Define property key class with `value_t` that must be `property_value`
-//     with the first template argument being the property class itself. The
-//     name of the key class must be the property name suffixed by `_key`, i.e.
-//     for a property `foo` the class should be named `foo_key`.

 //  3. Add an `inline constexpr` variable in the same namespace as the property
 //     key. The variable should have the same type as `value_t` of the property
 //     class, e.g. for a property `foo`, there should be a definition
 //     `inline constexpr foo_key::value_t foo`.

-//  5. Specialize `sycl::ext::oneapi::experimental::detail::PropertyToKind` for
-//     the new property key class. The specialization should have a `Kind`
-//     member with the value equal to the enumerator added in 1.
-//  6. Specialize
-//     `sycl::ext::oneapi::experimental::detail::IsCompileTimeProperty` for the
