"A custom prefix will be added to the MediaWiki namespace whitelist - MediaWiki:Custom-*' - allowing free-form message names to be created."

Interesting. I think for the purposes of standarizing messages, it might be a good idea to simply move all non-standard pages to that namespace, although this might be problematic because some scripts depend on the proper names. Also, what exactly happens if wikia deploys a feature that uses a MediaWiki page used by a wiki, does the feature not work (or simply uses its default message), do you automatically move the page, or inform the wiki admins that they need to move it?

"We are continuing to roll out JS review process - while most reasonably active communities already have it enabled, we will soon be adding all communities which already have any community JS."

One good feature might be a way to actually sort the table in Special:Jspages. If one submits many reviews it becomes hard to go through the red and green maze to find out what has been approved. Perhaps there could be an actual notification (with dates) informing the admins that the new javascript is live rather than having to check the page every once and again. Also, the Special:Jspages doesn't have any help links or any information at all. Newer admins might be completely confused.

It might be a good idea to document the newer tabs in infoboxes. Tabbers seem to work differently from galleries, and I'm not entirely sure if the tabbers also work with other XML tags.
