twitter-to-sqlite focuses on archiving users, but does not easily support archiving conversations or community activity.

For reference, this is implemented in twarc, using a search, optionally recursively.

Other research suggests that this formerly, or currently, requires a search query, use of undocumented related_results api, or with requested inclusion of newer conversation_id with subsequent query.
