My biggest concern with this series in particular is that we're trying to break down an all-or-nothing change into smaller components. So if we landed four out of the five of those series, it would be better to have landed none of them, since the first four aren't really all that useful on their own. I suppose if we're relatively confident that the last series will be merged eventually, then that seems like less of a concern. But I'm not sure that we're at that point yet. > I wonder whether a compromise would be to continue sending complete > patch series, but explicitly point out "break points" in your patch > series.

I think that's a reasonable alternative. It does create a minor headache for the maintainer[^1], though, so I'd like to avoid it if possible. > > - The fourth series (which actually implements multi-pack reuse) still > > remains the most complicated, and would likely be the most difficult > > to review.

My preference is to avoid splitting the series if we can help it. But if you feel strongly, or others feel similarly, I'm happy to take another crack at breaking it up. Thanks for all of your review so far! Thanks, Taylor
