   Difficulties here include how to go from non-rtti pmr::memory_resource to the diagnostics interface type.

   This use case is supported in cetl::rtti via specializations of type_id_getter():

   CETL/include/cetl/rtti.hpp

   Lines 79 to 88 in 88fd7a3

   	/// The type ID getter for the given type.
   	/// This helper is provided for regularity; it returns the same value as \c T::_get_type_id_().
   	/// The type shall satisfy \ref cetl::has_type_id.
   	/// Specialize this getter to add RTTI support to types where it is not possible to define a static method
   	/// (e.g., builtins, pointers, third-party classes, etc).
   	template <typename T>
   	constexpr type_id type_id_getter() noexcept
   	{
   	return T::_get_type_id_();
   	}

   So we just specialize it for pmr::memory_resource and we're done
