Interesting. It seems that Google has no interest in looking radically different from other websites, as someone felt necessary for Wikimedia projects vs. the rest of MediaWikis.

Keep in mind that material design is also intended to be a design standard used in Android by third party developers and OEMs. They want people to pick this up, not to have a lot of unique design standards, because the usefulness of Android is dependent on a consistent look and feel. 

So Google distributing this is more akin to Wikimedia encouraging gadget and extension developers to use OOJS/OOUI, rather than encouraging third party installs of MediaWiki to do the same.
