I see, yeah, that makes sense.

That still doesn't cover the "notmuch unjoin" semantics i'd sketched out
earlier, though.  that might need to be a different use case.

The semantics would be something like:

  break the selected threads into threads based solely on their
  References headers (including any manual reference terms) using
  connected component analysis, restoring the threading to what would be
  produced on a clean import.

maybe "unjoin" is the wrong verb, but i'm open to suggestions.

i see, that makes sense.

right -- we don't even have any version information in the notmuch dump
file.  what's the right way to approach this?
