> As discuss links to either Discussions or Special:Forum, how does it react to those wikis with neither?

Considering that every wiki should have some way of allowing users to communicate, Special:Forum could work in every wiki and redirect to a place like Portal:Forum or a default discussions thread on every wiki.

This will likely only be a problem for older wikis though, new ones will always have that discussion entry point regardless of whether they use it or not.
