There are potentially many ways to accomplish what you describe. However,
the options Duncan listed in his original email are genuinely the easiest
ones any of those involved have come up with and the next best ideas are
either substantially less clear or substantially more work IMO.

Duncan also gave some evidence that the size increase is quite small.
Again, just IMO.
