@silverpill reading through the "conversation containers" doc at https://codeberg.org/streams/streams/src/branch/release/doc/develop/en/Containers.mc i have the following comments
- the notion of a "top level post" is kinda redundant with the context, and its definition as "without inReplyTo" can be problematic if your "top-level post" is actually a reply to something. imagine an article inReplyTo something, but with its own context
- "the conversation owner (target->attributedTo)" seems to confirm not 2.2...
