Feeds, the software which powers Discussions and now new Message Wall, does not support wikitext because it's not based on a wiki engine. Templating and warning macros have been captured as desired features for these features, but I have nothing to announce on that front at this time.

As a long-time Reddit moderator, I understand the value of macroing warnings and ban messages, so I would like to see this feature added to Feeds tech as well :)
