Code review

Let SPQRobin know.

I've left him a message.

I made the language names in Names.php lowercase where this is the case in the local spelling, so also for Galego -> galego. I have however no idea why it updates all the language names in the i18n files but not for Galician. I see it did update the name in MessagesGl.php. Strange...

Seems that it is now being updated in some extensions: [1], [2]. Isn't it?

Ah, indeed. Then I suppose all extensions will be updated sooner or later.
