On second though, I think it would be even better if we moved these back to the wiki itself. There is no need to export these strings. It can either be done as translatable page or unstructed element translation message group. I prefer translatable page approach as it is easier to use (no need to remember to update some other unrelated page) and does change tracking which the latter doesn't.

@Nikerabbit Great idea. Lets make it a translatable page.
