I didn't want to reply to not sound too opinionated (ironically) but I agree. Chains feel cool when you write them down but don't always scale and lead to mistakes as Sileni points out. BTW, as an addition to my original comment, a good example of reinventing types are the litany of C++ libraries that do NOT use the STL but reinvent half of it.
