New messages that should be optional
Appearance
I believe the recent update invalidated the one optional message we have, and that it should be replaced with Osm:Wmt-d39fbf478176b9ed008faf0cf0bfe88a778c7e9c-s_km and Osm:Wmt-978afcb7a6f02efbc6cf00a0668afa0913891cd3-s_m as there are only very few languages where these will need any tweaking (I don't understand why Siebrand has translated to nl), and the risk of the translator skrewing up the message is greater than the potential benefit.
