I believe Bitcoin currently enjoys the property that during an "innocent"
re-org, i.e. a reorg in which no affected transactions are being double
spent, all affected transactions can always eventually get replayed, so
long as the re-org depth is less than 100.
My concern with this proposed operation is that it would destroy this
property.
