I intuitively expected, and I think most often would want, the first key to be held. The reason being that I would except most often the initial insertion to be the canonical form.
My stock ticker example (but from a real problem I had a few days ago) would want to have this example: I want the first key, because I'm pre-seeding the dict with a variety of keys that are of the canonical form.
Whichever way is adopted, I think even if you say it's implementation specific, people will end up relying on it in their code.
