WikiActivity as a feature was considered for removal as it's a custom code for Fandom, but the community feedback made them at least rethink that (though we haven't heard a final answer on it yet so keep clamoring).

Message Wall is a cool thing, but it's a mess MediaWiki wise. The new format is based on Discussions, and I'm definitely going to miss MediaWiki. Plenty of wikis have boilerplate templates for things like not following a changes or faulty image uploads. I've asked for a way to make some preset messages, but it got lost in the conversation and wasn't answered. Arguably you could maintain a text file with some common messages, but that's not helpful if you're on mobile.
