Wikitext didn't disappear in UCP system, it's no more available in Article Comments and Message Wall due to the fact they don't run onto the MediaWiki basecode, and they can't be without hard development to recreate wikitext parser.

WikiActivity was not brought away, just because it's not a standard feature and so, it doesn't exist. To port WikiActivity on UCP plateform, Fandom should change standard basecode, but if they do that, they will encounter the same obstacles for future updates. Will said many times they're studying how to port WikiActivity on UCP, so stay tunes for future announcement about next features.
