notafish reports that the book tool doesn't display on Grants_talk namespace pages. https://meta.wikimedia.org/w/index.php?title=User_talk:Nemo_bis&oldid=prev&diff=10309237

Indeed, we have:

'wmgCollectionArticleNamespaces' => array(
'default' => array(

		NS_MAIN, NS_TALK, NS_USER, NS_USER_TALK, NS_PROJECT, NS_PROJECT_TALK, NS_MEDIAWIKI, NS_MEDIAWIKI_TALK,
		NS_HELP, NS_HELP_TALK, 100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111

),
'+enwikisource' => array( 114 ), // bug 56899
'+metawiki' => array( 200 ),
),

Which is working as advertised.

I'm not sure why we're doing all this just to exclude a handful namespaces, but clearly all custom namespaces are supposed to be added and we just forgot the "new" Meta-Wiki ones from 201 to 209.
