That's because the new comments and message walls run on an entirely different technology, just like Discussions. They don't use MediaWikia, and therefore aren't hooked into Recent Changes, nor do they support creating links via wikitext.

We're aware that users do need some way to monitor social activity on their wiki, and are looking into how to solve that problem. The lack of link auto completion and the broken galleries are also issues we're aware of and already working on fixing.
