The only patch left unmerged is: https://gerrit.wikimedia.org/r/#/c/169716/

I'd merge it but it should really be merged and monitored by whoever does the next swat deploy?

This can be merged and deployed at any time that someone is willing to either run l10nupdate manually or wait until the nightly run.

Can it be effectively tested on beta cluster?

I was just about to ping on this, but then noticed that the patch above ( https://gerrit.wikimedia.org/r/#/c/169716/ ) was merged and deployed yesterday morning by @Nikerabbit and @Krenair. Thanks!
