This bug is to enable subpages on the (main) namespace on be.wikimedia.org, so the [[meta:Template:Languages]] could be used.
Also the project namespace (I thought it were enabled by default, but apparently not).
Code review: https://gerrit.wikimedia.org/r/11723
I have deployed the change on the live cluster.
