I guess I should say why I'm concerned with the idea... Precedents should be set sooner rather than later. If the wiki does eventually get more traffic, it's much easier to follow comments when they're organized by topic than by time period, if at all. Maybe some sort of bootstrap method would work, though.

The former Wikipedia editor in me doesn't like the copy-paste solution, as it bypasses the wiki edit tracking system and the comment thread system here. (If you thought retributive downvoting was bad, this can potentially be much worse if someone has a grudge and is clever about it.)

All this talk is making me want to create a wiki account; I will do so tonight when I get home.
