Language selection in WFS

Is the language selection in WFS only meant to test the watch faces in different languages and fonts, or does the selection represent the languages currently supported by Wear OS?
I’m asking because due to certain limitations of WFS, I’m considering whether it’s worth bypassing the limitation with bitmaps. The selection that WFS offers would be just about manageable, the selection that the phone OS offers is not.

@BFD As far as I know the “RUN” section on the watch face studio is meant to simulate the watch face, how it would look on your watch. To test it on a specific device you would need that device or an emulator.

I couldn’t find any information on if the selection represent all the languages supported by WearOS but it seems like it does.
