hmmm, I'm not sure how Otel deals with created metrics. I am tempted not to have any MUSTs around names so that we can truly allow anything and not be against the spec (no matter how much we discourage it)

I think we need a MUST for the _created series, otherwise it wouldn't be the _created series :).
