I haven't tested your code, I am sure it is useful, I just have one 
thing to note: Are you aware of the --threshold command-line switch for 
script/build/output-distance.py? I wonder if setting it to a lower 
default value would not reveal the "missing" regtest changes that you 
are presumably looking for.
