what's the benefit of the integration? the transient back and forth conversations of a debate don't need to be co-located with the longer-lived artifacts-- the signal/noise ratio would probably actually harm effective communication.

I actually wonder, on a highly trafficked Wave with many subthreads, if the OP doesn't have trouble figuring out which parts are relevant and need to be promoted or flagged as a more authoritative/final artifact of a discussion, and which are just unproductive tangents? (especially since Wave doesn't let you reparent your comment if you've accidentally put it at the wrong hierarchy level. It also doesn't let you delete comments! wtf?)
