Technically, every message wall uses wikitext because that's how the legacy system is built.

We looked at usage of the source mode, which would indicate desire to use more advanced formatting beyond what Feeds tech can offer.

We're doing some user feedback research on advanced formatting gaps in Feed tech to understand where better solutions can be found going forward. Wikitext as prescriptive design is an expensive and potentially unnecessary ask, given the data, so we want to see how we can fill the gaps in more user-friendly ways that are easily maintainable.
