Your comment is spot on. We're discussing technical ideas for something that isn't even clear on a semantic level. Somehow this whole discussion reminds me of this blog post [1], in particular the "Lack of Permanent IDs" section. A "Conceptual Object" as it is described in that blog post sounds like a great idea, yet it suffers from the same real world semantic issues that Martin already pointed out.
