Notifications for non-UCP message walls will not be added. Fandom sees it as a waste of time to incorporate that feature into UCP since all wikis will be converted to UCP and thus, eventually, there will be no non-UCP message walls to get notifications from. That was their logic behind not having it for Discussions and that was 4+ years ago.

Regarding the Template:Animangafooter, there were previously 2 issues: At the time you created this thread, interwiki transclusion had already been fixed for some time. The fact that the template works indicates that the hotlinking issue is now also fixed.
 * 1) Interwiki transclusion wasn't working
 * 2) Hotlinking images wasn't working
