That is how I keep it in my tree - but the intermediate entries don't build, so its only
useful for keeping my sanity.

I don't think the intermediate points are useful, it would be better to spend the time
generating confidence that this thing doesn't introduce any functional changes - if it
does, it should be reverted.

To that end:
So far I've done this by hand, but recently cooked a python script to generate this. I'll
include this in the next version instead. Hopefully this is a better way do demonstrate
'nothing up my sleeve' - it certainly makes it easier to regenerate this after other
series have been merged.

Obviously I'm not expecting this to be merged as is - as suggested in the cover letter we
need to find a least disruptive moment.


Thanks,

James
