How is flagging going to work with the new nested comments?

If I flag a comment as rude/abusive, but it has replies, do those replies get removed with the parent? Are entire threads removed if the parent is deemed to meet removal criteria, regardless of whether a nested comment might stand on its own merit?

Consider a situation where someone makes a legitimate comment but does so in a rude/abusive/unfriendly way. There are threaded replies that are added in response to the legitimate comment, but the parent itself should be removed because it violated SO policies.

Or a situation where there's a clarifying comment added asking for some particular details. In the underlying thread, some additional comments bring up additional points. The parent comment is addressed via post edits; the nested comments are outstanding. The parent comment can legitimately be removed as no longer needed, but the nested comments might not.
