Mike, this proposal was purposefully constructed to maintain as well as
possible the semantics of Satoshi's original construction. Higher sequence
numbers -- chronologically later transactions -- are able to hit the chain
earlier, and therefore it can be reasonably argued will be selected by
miners before the later transactions mature. Did I fail in some way to
capture that original intent?
