I suspect that you'll end up measuring no change assuming that you
(AFAIK) use bitmaps and (I imagine) delta islands in your production
configuration? This series is not compatible with either of those
features to my knowledge.
You are correct that this is not compatible with those features as-is.
_Maybe_ there is potential to integrate them in the future, but that
would require better understanding of whether the new compression
mechanism valuable in enough cases (final storage size or maybe even
in repacking time).
At the very least, it would be helpful if some other large repos were
tested to see how commonly this could help client-side users. Are
there other aspects to a repo's structure that could be important to
how effective this approach is?
