Right. I pointed at something that your iteration 0 notion of a local
managed patch set didn't handle. You said (in effect) "no problem,
we'll make the local patches history diffs rather than action diffs."

Remember the first premise, that a dump file is just a history diff
on the empty tree? A repo is nothing but a sequence of history diffs.
The moment that you say your local objects are history diffs, *you've
just reinvented the repo*!

And that was the sound of "local patch management" going down the crapper.

Reasonable. I'm not entirely happy with it myself and am trying to
come up with a better way.
