63  I extremely dislike the inversion to preserve the "previous nSequence
64  semantics". The "previous nSequence semantics" were
65  consensus-unenforceable but we can cover the same use cases (or the
66  realistic ones at least) with nMaturity. Let's face it and move on
67  without technical debt we don't need and may regret. If we do this
68  inversion we will likely carry it for very long if not forever.
69  As a side effect, I believe documentation can become much clearer
70  (maybe even shorter simultaneusly).
