Promoting replies / demoting posts on P2?

Would anyone else find it useful to be able to promote a reply as a separate post, and to demote a post to a reply under another post? Context & explanation, plus a technical update, follow.

I see the chronological flow of posts on a P2 as being useful for tracking the evolution of projects or helping new members get up to speed. Along the way, however, people unfamiliar with the system may post replies or snippets of thoughts in a way that might fit better as replies under posts. On the flip side, a reply may be so well thought out that it seems a shame for it to be hidden from the main view under another post. So part of the issue here is another question: Is this an issue anyone else has observed?

Obviously one solution is to manually shift these as appropriate (or delete posts that are unintentional non-sequiteurs), but that introduces other problems (whoever makes the shift is the “author” and the new post/reply will have a new timestamp). So I wondered if it might be possible to have a simple way to recategorize a reply as a post, or post as reply in the flow.

I understand from Jon in an email exchange that this is not currently technically possible. So, this post is mainly to sound out whether the concept is one that makes sense to others, and thus should be considered for development.

Examples in other worlds

The simplest example of the promote/demote concept is of course a dynamic list (ordered or unordered) such as one has in a wordprocessor or many other programs like WordPress itself: typically tab to demote, and alt-tab to promote.

Another example of promotion is the feature current on LinkedIn where, upon making a long reply to another post, one is automatically given the option to “start a new conversation” by taking the reply up a level as a separate post.
