With the latest version of the language pack, version 1.5.0, you can now select between standard (what we had before) and formal language in the admin cp under this extensions settings tab. The core and first party/bundled extensions are fully translated for formal and standard, for third party translations please help us by providing translations to the formal weblate repository if they differ from the standard version. Do not provide translations to that repository that would be the same for standard and formal, since Weblate exports the formal variant by merging standard and formal, overwriting all standard translations in the process that contain a formal translation.
I have also generally overhauled all core and bundled extension translations in this process.
