In the big multilingual sites with many numbers of translatable pages, using 'Special:AggregateGroups' may be unuseful. See as example meta:Special:AggregateGroups.

In my opinion, strongly needs automatic table of content (list of aggregate groups).

Or, alternatively, collapsible mode for each group (with default state as "collapsed")
