Hmm, really? IIUC I did not modify 0001 and 0002 patches, I just re-assigned the
version number. I compared between yours and mine, but no meaningful differences
were found. E.g., following command compared v4-0002 and v16-0002:
```

I have no strong opinion, but it may be useful to keep them pluggable.
