The tension is that people want to reuse translations. So maybe you have the story board for the first version. Then, someone makes a new button. In Django, they'd put _("Open ticket") as the text, see there's already a translation, and think they're good to go. Sure, having every page looked at by a translator for every language every time you make a change would be ideal, but also a bit costly and slow. I think there are better options in the middle.

> Also, you should test you translations. Some of the translations that I've seen (even from reputable companies) are so bad that it's pretty obvious no native speaker has ever looked them over.

Testing is a must. Before I fixed + linted it, we often had community-provided translations which would cause the app to crash due to missing/additional format strings.
